Manganese(II) in Tetrahedral Halide Environment: Factors Governing Bright Green Luminescence

Finding narrow-band light emitters for the visible spectral region remains an immense challenge. Such phosphors are in great demand for solid-state lighting and display application. In this context, green luminescence from tetrahedrally coordinated Mn(II) is an attractive research direction. While the oxide-ligand environment had been studied for decades, much less systematic efforts have been undertaken with regard to halide coordination, especially in the form of fully inorganic halide matrixes. In this study, we synthesized a series of hybrid organic-inorganic Mn(II) halides as well as a range of fully inorganic Zn halide hosts (chlorides, bromides, iodides) doped with Mn(II). In the latter, tetrahedral coordination is attained via substitutional doping owing to the tetrahedral symmetry of Zn sites. We find that the choice of the halide as well as subtle details of the crystal structure profoundly govern the photoluminescence peak positions (500-550 nm range) and emission line widths (40-60 nm) as well as radiative lifetimes (shorter for iodides) through the altered ligand-field effects and degrees of spin-orbit coupling. The photoluminescence quantum yields were as high as 70-90%. The major hurdle for the practical use of these compounds lies in their low absorption coefficients in the blue spectral regions.

A novel strong AIE bi-component hydrogel as a multi-functional supramolecular fluorescent material

Multi-functional supramolecular fluorescent materials are an intriguing concern for materials science. Herein, an easily prepared bi-component hydrogel with strong aggregation-induced emission (ME) (MQ-G) was successfully constructed by the gelators naphthalimide derivative (M) and tri-(pyridine-4-yl)-functionalized trimesic amide (Q) in DMSO-H2O (6 : 4, v/v) via pi – pi, hydrogen bond and pi – electron donor-acceptor interactions. The obtained bi-component hydrogel MQ-G has an excellent self-healing property. Interestingly, the MQ-G exhibits strong orange AIE, the fluorescence quantum yield of the MQ-G was measured as 0.578. Moreover, the MQ-G could successively sense Fe3+ and H-2 PO4- in water through a fluorescent ON-OFF-ON pathway, which suggests the MQ-G could serve as an ON-OFF-ON fluorescent material and efficient logic gate. Meanwhile, the xerogel of MQ-G is capable of removing Fe3+ at an adsorption rate of 99.74% in diluted aqueous solution. Moreover, the thin films based on the MQ-G and MQ-G + Fe3+ were also prepared, which could not only act as supramolecular fluorescent material but a simple and efficient tool for detection Fe3+ and H2PO4-, respectively.

Mixed Organometallic-Organic Hybrid Assemblies Based on the Diarsene Complex [Cp2Mo2(CO)(4)(mu,eta(2)-As-2)], Ag-I Salts and N-Donor Organic Molecules

The reaction of the organometallic diarsene complex [Cp2Mo2(CO)(4)(eta(2)-As-2)] (1) with Ag[Al{OC(CF3)(3)}(4)] (Ag[TEF]) yielded the Ag-I monomer [Ag(eta(2)-1)(3)][TEF] (2). This compound exhibits dynamic behavior in solution, which allows directed selective synthesis of unprecedented organometallic-organic hybrid assemblies upon its reaction with N-donor organic molecules by a stepwise pathway, which is supported by DFT calculations. Accordingly, the reaction of 2 with 2,2 ‘-bipyrimidine (L1) yielded the dicationic molecular compound [{(eta(2)-1)(2)Ag}(2)(mu-L1)][TEF](2) (3) or the 1D polymer [{(eta(2)-1)Ag}(mu-L1)](n)[TEF](n) (4) depending on the ratio of the reactants. However, its reactions with the pyridine-based linkers 4,4 ‘-bipyridine (L2), 1,2-bis(4-pyridyl)ethylene (L3) and 1,2-bis(4-pyridyl)ethyne (L4) allowed the formation of the 2D polymers [{(eta(2)-1)Ag}(2)(mu-Lx)(3)](n)[TEF](2n) [Lx=L2 (5), L3 (6), L4 (7), respectively]. Additionally, this concept was extended to step-by-step one-pot reactions of 1, [Ag(CH3CN)(3)][Al{OC(CF3)(2)(CCl3)}(4)] ([Ag(CH3CN)(3)][TEFCl]) and linkers L2-L4 to produce the 2D polymers [{(eta(2)-1)Ag}(2)(mu,Lx)(3)](n)[TEFCl](2n) [Lx=L2 (8), L3 (9), L4 (10), respectively].

The in situ grafting from approach for the synthesis of polymer brushes on upconversion nanoparticles via NIR-mediated RAFT polymerization

We report the first example of in situ polymer brush growth on the surface of upconversion nanoparticles (UCNPs) in a one-pot near-infrared (NIR) light mediated reversible addition-fragmentation chain transfer (RAFT) polymerization. In the process of polymerization, the surface growth of polymer brushes was realized through an efficient in situ ligand exchange between a photo-activated chain transfer agent (CTA) and the ligand groups on the surface of UCNPs. BF4- was found to be the most efficient ligand in comparison with oleic acid and pyridine. The 980 nm NIR-mediated RAFT polymerization exhibits good temporal control with a low dispersity (M-w/M-n < 1.30), and the thickness of the polymer brushes can be easily adjusted by changing the polymer molecular weight and light exposure time. Moreover, the growth of polymer brushes can proceed even if there is a barrier (e.g. chicken skin) outside the reactor due to the excellent penetration ability of the NIR light. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 24057-28-1.

Bright Long-Lived Circularly Polarized Luminescence in Chiral Chromium(III) Complexes

A series of highly emissive inert and chiral CrIII complexes displaying dual circularly polarized luminescence (CPL) within the NIR region have been prepared and characterized. The helical [Cr(dqpR)(2)](3+) (dqp= 2,6-di(quinolin-8-yl)pyridine; R= OCH3, Br or C=CH) complexes were synthesized as racemic mixtures and resolved into their respective PP and MM enantiomers by chiral stationary phase HPLC. The corresponding enantiomers show large glum similar to 0.2 and high quantum yield of up to 17%, which afford important CPL brightness of up to 170 m(-1)cm(-1), a key point for applications as chiral luminescent probes. Moreover, the long-lived CP-NIR emission provided by these chromophores (ms range) in aqueous solution opens the way toward the quantification of chiral targets in biological systems with timegated detection. Thus, such chiral chromophores based on earth abundant and inert 3d metals open new perspectives in the field of CPL and represent an alternative to precious 4d, 5d and to labile 4f metal-based complexes.

Automated solution-phase syntheses of alpha 1 -> 2, 1 -> 3 type rhamnans and rhamnan sulfate fragments

Rhamnan and rhamnan sulfate are naturally occurring carbohydrates that have important biological functions and possible therapeutic applications, but studies are limited to the microheterogeneous mixtures from natural sources. This work reports the first synthesis of any sulfated rhamnan fragments and successful automation of the process with a recently developed automated solution-phase approach using N-iodosuccinimide/trimethylsilyl triflate (NIS/TMSOTf) promotor and levulinoyl ester deprotection conditions. The automated solution-phase activation/deprotection approach was initially able to create alpha 1 -> 2, 1 -> 3 type rhamnan di- and trisaccharide in moderate yields. Once these targets were achieved, a process to use SO3 center dot pyridine complex in DMF for sulfation compatible with an automated solution-phase liquid handling system was developed and successfully applied to carbohydrate sulfation to create two rhamnan sulfate fragments with differing monosulfation patterns.

4-(Dimethylamino)pyridine N-Oxide-Catalyzed Macrolactamization Using 2-Methyl-6-nitrobenzoic Anhydride in the Synthesis of the Depsipeptidic Analogue of FE399

A depsipeptidic analogue of FE399 was efficiently synthesized mainly through macrolactamization using 2-methyl-6-nitrobenzoic anhydride (MNBA), and a detailed investigation of the desired 16-membered macrolactam core of FE399 was performed. It was determined that the combination of MNBA and a catalytic amount of 4-(dimethylamino)pyridine N-oxide exhibits much higher activity than that of conventionally used coupling reagents such as hexafluorophosphate azabenzotriazole tetramethyl uronium and benzotriazol-1-yl-oxytripyrrolidinophosphonium hexafluorophosphate.

Hydrogenation of levulinic acid to valeric acid over platinum-tungsten catalysts supported on gamma-Al2O3

To address the challenges associated with fossil fuel depletion, exploration of the sustainable energy resources is one of the most pursued research areas in this century. Valeric acid (VA) is considered as a valuable platform molecule for the production of biofuels and chemical intermediates. However, the production of VA from levulinic acid (LA) has become one of the most desirable reactions. The aim of this work was to investigate the amount of acidity, Pt loading and experimental conditions for the hydrogenation of LA into VA operated at 0.1 MPa H-2 pressure and to elucidate the relationship between the active sites and the catalytic performance. The Pt-WO3 catalysts supported on gamma-Al2O3 were synthesized by a simple wet impregnation method with various Pt loadings from 0.5 to 3 wt% with constant 10 wt% of WO3 and calcination at 500 degrees C for 4 h under air. The catalysts were characterized by powder X-ray diffraction (XRD), scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS), N-2 adsorption-desorption, temperature programmed desorption of ammonia (NH3-TPD), pyridine Fourier transform infrared spectroscopy (Pyr.FT-IR) and CO-chemisorption studies. Under optimized reaction conditions, the 2Pt-10WO(3)/gamma-Al2O3 catalyst exhibited the highest selectivity to VA (58%) with 91% conversion of LA. This is due to the availability of a huge number of acidic and Pt active sites on the catalyst surface. In addition, the catalytic activity, reaction parameters and stability of the catalyst are demonstrated clearly.

Comparative study of block copolymer-templated localized surface plasmon resonance optical fiber biosensors: CTAB or citrate-stabilized gold nanorods

Block copolymer (BCP) brush-like layer absorbed on optical fibers are shown to address the longstanding challenge of forming dense and well-dispersed gold nanorods (AuNRs) films on highly curved surface, allowing the development of real-time localized surface plasmon resonance (LSPR) biosensors for antigen-antibody interaction. This method requires only solution-based manufacturing processes and a plasma cleaning step to self-assemble AuNRs with various aspect ratios on the optical fibers. Because AuNRs capped with cetyltrimethylammonium bromide (CTAB) have been problematic for biosensing applications due to their cytotoxicity and displacement difficulty in the construction of biosensors, citrate-stabilized AuNRs were prepared from CTABstabilized AuNRs via surfactant exchange. For comparison, both a poly(styrene)-b-poly(acrylic acid) (PS -b-PAA) BCP template with CTAB-stabilized AuNRs and a poly(styrene)-b-poly(4-vinyl pyridine) (PS-b-P4VP) BCP template with citrate-stabilized AuNRs were employed for the fabrication of the optical fiber biosensor. The LSPR spectral analysis results demonstrate that the sensitivity of the sensor produced by the PS-b-P4VP templating method was 1.5 times better than that of the sensor produced by the PS -b-PAA templating method, which was due to the improved surface coverage and reduced aggregation of nanoparticles. The detection limit of the PS-bP4VP-templated sensor for human IgG was 0.6 nM. Furthermore, for citrate-stabilized AuNRs, the PS-b-P4VP templating method also led to a better surface morphology and higher sensitivity as compared to the standard particle absorption methods using alkoxysilanes or polyelectrolytes on identical fibers. The simplicity of the fabrication process and the far superior optical performance of the PS-b-P4VP-templated LSPR optical fiber sensor illustrate the ability to regulate the detection range by tuning the aspect ratios of the AuNRs, and demonstrate its application prospects as a real-time biosensor without cytotoxicity.
