Reaction of NdIII and ErIII nitrate salts with a 1,3,5-tris(dipicolylamine)-triazine (dpat) ligand yielded two unprecedented examples of [Ln(NO3)6/5]3-/2- (Ln = Nd, Er) moieties completely encapsulated by the ligands. They are found in the two new complexes, [(H3dpat)2][(Nd(NO3)6)2]·2CH3CN (1), and the related [(H3dpat)2][(Er(NO3)5)3]·3CH3CN·2H2O (2). The structures of the complexes are similar and they crystallize in the triclinic P-1 space group with a 12.1630(3), b 12.2694(3), c 17.6357(5) Å, and a 14.3372(4), b 17.1271(4), c 25.2207(7) Å, resp. Anion-π interactions, which are reported here for the first time for LnIII ion complexes, hydrogen bonding interactions and π-π stacking support the formation of the encapsulated species. Evidence of the protonated dpat ligand in 1 and 2 was found through isolation of (H2dpat)(NO3)2. Finally, the pH-dependent ability of the ligand to extract LaIII and nitrate ions from aqueous into toluene solution is demonstrated.

Product Details of 1539-42-0In 2020 ,《A 4,5-quinolimide-based fluorescent sensor for sequential detection of Cu2+ and cysteine in water and living cells with application in a memorized device》 appeared in Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy. The author of the article were Zhang, Yu; Li, Lan; Wang, Jinping; Jia, Lihua; Yang, Rui; Guo, Xiangfeng. The article conveys some information:

A new 4,5-quinolimide-based fluorescent sensor BNC was synthesized and characterized. BNC showed single selectivity for Cu2+via the “”turn-off”” fluorescence among various common metal ions. After forming a 1:1 stoichiometric complex with Cu2+, the detection limit (LOD) of BNC for Cu2+ is 0.44μM. Subsequently, the in situ generated BNC-Cu2+ complex had been used for sensing Cys with the LOD of 1.5μM through the displacement strategy, resulting in the revivable emission of BNC. According to the “”off-on-off”” fluorescence cycle of BNC generated by the alternate addition of Cu2+ and Cys, a reversible memorized device with “”read-write-read-erase”” behavior was constructed at the mol. level. Furthermore, the recoveries of Cu2+ in lake water with BNC were at 95.0-105%. And sequential fluorescence imagings of BNC for Cu2+ and Cys were successfully applied in living yeast cells.Bis(pyridin-2-ylmethyl)amine(cas: 1539-42-0Product Details of 1539-42-0) was used in this study.

In 2022,Fischer, Kim; Krahmer, Jan; Tuczek, Felix published an article in Zeitschrift fuer Naturforschung, B: A Journal of Chemical Sciences. The title of the article was 《Chemically and Light-Driven Coordination-Induced Spin State Switching (CISSS) of a nonheme-iron complex》.Synthetic Route of C12H13N3 The author mentioned the following in the article:

The new Fe(II) complex [Fe(trident)(bmik)](ClO4)2 (1) (trident = bis(2-pyridylmethyl)benzylamine and bmik = bis(1-methylimidazole)ketone) exhibits a change of magnetic moment in dichloromethane (DCM) solution upon addition of pyridine which is attributed to the Coordination-Induced Spin State Switching effect (CISSS). By attaching a photoisomerizable azopyridine sidegroup to the tridentate ligand the complex [Fe(azpy-trident)(bmik)](ClO4)2 (2; azpy-trident = [N,N-bis(2-pyridylmethyl)]-3-(3-pyridylazo)benzylamine) is obtained. As detected by Evans NMR spectroscopy, 2 reversibly changes its magnetic moment in homogeneous solution upon photoirradiation which is attributed to intermol. Light-Driven Coordination-Induced Spin State Switching (LD-CISSS). Further support for this interpretation is inferred from concentration-dependent Evans NMR measurements.

And the article was published in Microbial Drug Resistance (New Rochelle, NY, United States) in 2019. Computed Properties of C12H13N3 The author mentioned the following in the article:

Carbapenem-resistant Enterobacteriaceae (CREs)-mediated infections remain a huge public health concern. CREs produce enzymes such as metallo-β-lactamases (MBLs), which inactivate β-lactam antibiotics. Hence, developing efficient mols. capable of inhibiting these enzymes remains a way forward to overcoming this phenomenon. In this study, we demonstrate that pyridyl moieties favor the inhibitory activity of cyclic metal-chelating agents through in vitro screening, mol. modeling, and docking assays. Di-(2-picolyl) amine and tris-(2-picolyl) amine exhibited great efficacy against different types of MBLs and strong binding affinity for NDM-1, whereas 2-picolyl amine did not show activity at a concentration of 64 mg/L in combination with meropenem; it further showed the lowest binding affinity from computational mol. anal., commensurating with the in vitro screening assays. The findings revealed that the pyridyl group plays a vital role in the inhibitory activity of the tested mols. against CREs and should be exploited as potential MBL inhibitors.

《A copper complex based catalytic conversion and isolation of carbonate from CO2 for the carbon sequestration process》 was published in Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands) in 2020. These research results belong to Sivanesan, Dharmalingam; Seo, Bongkuk; Lim, Choong-Sun; Kim, Hyeon-Gook. Recommanded Product: Bis(pyridin-2-ylmethyl)amine The article mentions the following:

The conversion of CO2 into value-added chems. of industrial significance is of great interest due to global warming-related concerns and the depletion of natural resources. This paper describes a mononuclear copper complex with an N3S coordination environment that can catalyze the conversion of CO2 into the carbonate anion with an ambient O2. Electrochem. studies indicate that the N3S-ligated Cu(II) complex can be reduced to Cu(I), which can subsequently generate the carbonate anion from CO2 and ambient O2. In presence of LiClO4 when the N3S-ligated complex Cu(II) is reduced to Cu(I), the complex easily releases the carbonate anion which easily precipitates as Li2CO3 in CH3CN. These studies suggest that the N3S-ligated Cu(II)/(I) complexes can be used to convert CO2 to carbonate and isolate the generated carbonate.

Benazzi, Elisabetta; Begato, Federico; Niorettini, Alessandro; Destro, Lorenza; Wurst, Klaus; Licini, Giulia; Agnoli, Stefano; Zonta, Cristiano; Natali, Mirco published their research in Journal of Materials Chemistry A: Materials for Energy and Sustainability in 2021. The article was titled 《Electrocatalytic hydrogen evolution using hybrid electrodes based on single-walled carbon nanohorns and cobalt(II) polypyridine complexes》.Electric Literature of C12H13N3 The article contains the following contents:

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 molH2 molCo-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. In the experiment, the researchers used many compounds, for example, Bis(pyridin-2-ylmethyl)amine(cas: 1539-42-0Electric Literature of C12H13N3)
