Benazzi, Elisabetta;Begato, Federico;Niorettini, Alessandro;Destro, Lorenza;Wurst, Klaus;Licini, Giulia;Agnoli, Stefano;Zonta, Cristiano;Natali, Mirco research published 《 Electrocatalytic hydrogen evolution using hybrid electrodes based on single-walled carbon nanohorns and cobalt(II) polypyridine complexes》, the research content is summarized as follows. The generation of hydrogen from water represents an important task towards a carbon neutral economy. Within this context, the preparation of hybrid electrodes merging the versatility of solid-state porous substrates and the catalytic ability and tunability of mol. complexes represents a great challenge. In the present work, we report on the preparation of hybrid cathodes for the hydrogen evolution reaction (HER) through an unprecedented combination of single-walled carbon nanohorns (SWCNHs) and two novel cobalt(II) polypyridine complexes based on the tris(2-pyridylmethyl)amine (TPMA) ligand scaffold. Suitable pyrene groups are introduced in the ligand framework in different positions to provide a way for direct anchoring onto the carbonaceous substrate by exploiting non-covalent π-π interactions. The present systems behave as competent cathodes for the HER in neutral aqueous solution with overpotentials of η ~0.5 V and stable current densities (within 1 h electrolysis) up to -0.50 mA cm^-2, whose exact values depend on the catalyst used and are mainly related to the resp. loading on the electrode surface. In both cases, hydrogen evolution is detected under continuous electrolysis for up to ca. 12 h leading to maximum turnover numbers (TONs) of 4700 and 9180 mol_H2 mol_Co^-1 for the two different complexes. The progressive deactivation under electrolytic conditions is mainly ascribed to leaching of the metal center from the polydentate ligand, likely occurring from the competent catalytic intermediates involved in the HER.

Facile rare-earth triflate-catalyzed esterification of cellulose by carboxylic anhydrides under solvent-free conditions

We report here the facile rare-earth triflate-catalyzed esterification of cellulose by carboxylic anhydrides, including acetic anhydride, at room temperature under solvent-free conditions. As a model, D-glucose was peraceylated using only equimolar amounts of acetic anhydrides against hydroxyl groups to give the expected 1,2,3,4,6-pentaacetyl alpha-D-glucopyranoside (crude yield 98%, 68% yield after recrystallization) under solvent-free condition. In the case of powdery micmcrystalline cellulose, acetylation proceeded both in the absence of pyridine and solvent to give peracetylated cellulose, even in the bulk. From H-1 NMR measurements, the degree of substitution (DS) was 3.0 (100% acetylation) and we concluded that Sc(OTf)(3) -catalyzed solvent-free esterification of cellulose had taken place. The number-average molecular weight (M-n), calculated using the H-1 NMR intensity ratio based on the anomeric proton in the reducing terminus, was 1.7 x 10(4) (repeating unit of pyranose unit: 56).

Selective sensing and visualization of pesticides by ABW-type metal-organic framework based luminescent sensors

A new ABW-type luminescent metal-organic framework (MOF) namely (H3O)[Zn2L(H2O)]3NMP6H(2)O (1), constructed with eco-friendly Zn2+ and the multicarboxylate intraligand (LH5) was designed, synthesized and fully characterized by X-ray single-crystal diffraction, steady-state absorption and emission spectroscopy, and SEM observations. The MOF-based suspension sensor 1 (NMP) demonstrated high sensitivity to low-concentration pesticides of chlorothalonil (CTL), nitrofen (NF), trifluralin (TFL), and 2,6-dichloro-4-nitroaniline (DCN), which was assigned to the synergistic effect of the photoinduced electron transfer and the fluorescence resonance energy transfer. With the highest luminescent detection efficiency (K-SV up to 11.194 mu mol(-1) and LOD down to 2.93 ppm) to DCN, 1 (NMP) was successfully applied for the selective sensing of DCN. The MOF-based film sensor 1 (film) illustrated the selective visualization sensing of trace amounts of DCN. In addition, based on the high saturated vapor pressure of TFL and the unique bathochromic shift effect to the emission maxima of 1, the MOF-based luminescent vapor sensing device 1 (LED) successfully exhibited operability for sensing of TFL vapor. The results illustrated a feasible approach to construct new MOF-based luminescent sensors for selective sensing and visualization of pesticides.

Nickel(II), copper(II) and zinc(II) complexes containing symmetrical Tetradentate Schiff base ligand derived from 3,5-diiodosalicylaldehyde: Synthesis, characterization, crystal structure and antimicrobial activity

Novel transition metal complexes of nickel(II), copper(II) and zinc(II) with a symmetrical tetradentate Schiff base, obtained by condensation of 1,3-diaminopropane and 3,5-diiodosalicylaldehyde, N,N ‘-bis(3,5-diiodosalicylaldehyde)-1,3-diaminoporpane (H2L), have been prepared and characterized by elemental (CHN), FT-IR, UV-Vis and H-1 NMR spectroscopic techniques. Out of these, copper (Cu(L)) and zinc (Zn(L)) complexes were isolated in the form of single crystals and characterized by single-crystal X-ray diffraction studies. In the Cu(L) complex, the geometry was found to be slightly distorted square planar, whereas the Zn(L) complex adapted slightly distorted octahedral geometry due to the attachment of two pyridine rings. The antibacterial screening of the prepared compounds was carried out by taking two Gram-positive (Staphylococcus aureus and Bacillus cereus) and two Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacterial strains. The appearance of zones of inhibition clearly depicted that the complexes have more retardation potential as compared to the Schiff base ligand.
