An Undergraduate Chemistry Laboratory: Synthesis of Well-Defined Polymers by Low-Catalyst-Concentration ATRP and Postpolymerization Modification to Fluorescent Materials

A two-session experiment is designed to introduce undergraduate students to concepts in catalysis, transition metal complexes, polymer synthesis, and postpolymerization modifications. In the first session, students synthesize poly(glycidyl methacrylate) via low-catalyst-concentration atom transfer radical polymerization (ATRP). The low-catalyst-concentration technique simplifies the experimental setup, reduces the cost of the synthesis, eliminates the need for catalyst removal from the product, and thus ultimately makes ATRP an environmentally benign process. In the second session, students modify the well-defined epoxide-containing polymers with nicotinamide in the presence of acetone, to afford fluorescent polymers.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 16858-01-8 is helpful to your research. Application of 16858-01-8

Visible Light-Induced CO-Release Reactivity of a Series of ZnII-Flavonolate Complexes

A series of zinc-flavonolate complexes of the general formula [(L)Zn(R)]ClO4 (L = TPA (tris-2-(pyridylmethyl)amine)), 6-MeTPA (N,N-(6-methyl-2-pyridyl)methyl)bis(2-pyridylmethyl)amine)), 6-Me2TPA (N,N-bis(6-methyl-2-pyridyl)methyl)(2-pyridylmethyl) amine), BPQA (bis(2-pyridylmethyl)(2-quinolinemethyl)amine), and BQPA (bis(2-quinolinemethyl)(2-pyridylmethyl)amine), R = FLH (flavonol), 4-MeOFLH (4-methoxyflavonol), and 4-MeOFLTH (4-methoxyflavothione)) have been prepared and characterised by X-ray crystallography, elemental analysis, FT-IR, ESI-MS, 1H NMR, 13C NMR, UV-vis and fluorescence spectroscopy. All the complexes can be induced to release CO by visible light (lambdamax ranges from 414 to 503 nm). The maximum absorption wavelength of the complexes followed the order 4-MeOFLTH > 4-MeOFLH > FLH. Exposure of the complexes to visible light under aerobic conditions results in oxidative C-C bond cleavage and almost quantitative CO release. Cytotoxicity tests showed that the complexes had a low toxicity to HeLa cells in the concentration range of 1 to 50 muM. These advantages indicate that the series of complexes are likely to be applied to biological systems.

Mechanism of water exchange on five-coordinate copper(II) complexes

The effects of temperature and pressure on the water exchange reaction of the five-coordinate complexes [Cu(tmpa)(H2O)]2+ and [Cu(fz2(H2O)]2- (tmpa = tris(2-pyridylmethyl)amine; fz= ferrozine = 5,6-bis(4-sulfonatophenyl)-3-(2-pyridyl)-1,2,4-triazine) were studied by employing 17O NMR spectroscopy. The former compound shows a solvent exchange rate constant kexof (8.6 ¡À 0.4) ¡Á 106 s-1 at 298 K and ambient pressure, within a factor of three of that for the corresponding process for [Cu(tren)(H2O)]2+ (tren = 2,2?,2?-triaminotriethylamine). The activation parameters DeltaH# DeltaS# and DeltaV# for the reaction are 43.0 ¡À 1.5 kJ mol-1, +32 ¡À 6 J K -1 mol-1 and -3.0 ¡À 0.1 cm3 mol-1, respectively. For [Cu(fz)2(H2O)]2-, Kex is (3.5 ¡À 2.6) ¡Á 105 s-1 at 298 K and ambient pressure, which is about an order of magnitude less than for [Cu(tren)(H2O)]2+. The DeltaH#,DeltaS# and DeltaV# values for the water exchange are 25.9 ¡À 2.2 KJ mol-1, -52 ¡À 7 J K -1 mol -1 and -4.7 ¡À 0.2 cm3mol-1 The activation volume is modestly negative for both reactions and therefore implies an associative interchange (Ia) mechanism. The results are discussed in reference to data for water exchange reactions of Cu(II) complexes available from the literature.

Bright lights down under: Metal ion complexes turning the spotlight on metabolic processes at the cellular level

The widespread uptake and use of emissive metal ion complexes for investigating cellular structure, composition and function, is evidence of the effectiveness and vast potential for this type of imaging probe. Metal ion complexes provide significant advantages over their organic fluorophore counterparts, including long emission lifetime, resistance to photobleaching and the capacity to readily modify their peripheral chemistry to target specific organelles, signalling pathways and individual molecules. This review will discuss recent progress in the development and use of metal ion complexes, specifically for studying metabolic diseases at the cellular level. Advanced metal ion complexes for organelle imaging and the detection of biorelevant species, to elaborate complexes for understanding cellular mechanisms and recent therapeutic applications will be reviewed. To align with the special issue, Coordination Chemistry Reviews: Coordination Chemistry in Australia, the work of Australian researchers actively engaged in this field is featured prominently, along with key developments from the global research community.

Synthesis, characterization, and photoresponsive properties of a series of Mo(iv)-Cu(ii) complexes

Six Mo(iv)-Cu(ii) complexes, [Cu(tpa)]2[Mo(CN) 8]¡¤15H2O (1, tpa = tris(2-pyridylmethyl)amine), [Cu(tren)]2[Mo(CN)8]¡¤5.25H2O (2, tren = tris(2-aminoethyl)amine), [Cu(en)2][Cu0.5(en)][Cu 0.5(en)(H2O)][Mo(CN)8]¡¤4H2O (3, en = ethylenediamine), [Cu(bapa)]3[Mo(CN)8] 1.5¡¤12.5H2O (4, bapa = bis(3-aminopropyl)amine), [Cu(bapen)]2[Mo(CN)8]¡¤4H2O (5, bapen = N,N?-bis(3-aminopropyl)ethylenediamine), and [Cu(pn)2][Cu(pn)] [Mo(CN)8]¡¤3.5H2O (6, pn = 1,3-diaminopropane), were synthesized and characterized. Single-crystal X-ray diffraction analyses show that 1-6 have different structures varying from trinuclear clusters (1-2), a one-dimensional belt (3), two-dimensional grids (4-5), to a three-dimensional structure (6). Magnetic and ESR measurements suggest that 1-6 exhibit thermally reversible photoresponsive properties on UV light irradiation through a Mo(iv)-to-Cu(ii) charge transfer mechanism. A trinuclear compound [Cu(ii)(tpa)]2[MoV(CN)8](ClO4) (7) was synthesized as a model of the photoinduced intermediate. The Royal Society of Chemistry 2011.
