Application of 15862-18-7, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 15862-18-7, name is 5,5′-Dibromo-2,2′-bipyridine. In an article£¬Which mentioned a new discovery about 15862-18-7
Organometallic networks based on 2,2?-bipyridine-containing poly(p-phenylene ethynylene)s
Conjugated polymers that comprise 2,2?-bipyridine moieties as part of the macromolecular backbone represent versatile precursors for the formation of conjugated metallo-supramolecular networks, which are readily accessible via ligand-exchange reactions. Poly{2,2?-bipyridine-5,5?- diylethynylene[2,5-bis(2-ethylhexyl)oxy-1,4-phenylene]ethynylene} (BipyPPE 1) and a statistical copolymer comprising 5,5?-diethynyl-2, 2?-bipyridine and 1,4-diethynyl-2,5-bis(alkyloxy)benzene moieties (BipyPPE2) were synthesized via the Pd0-catalyzed cross-coupling reaction of 1,4-diethynyl-2,5-bis(octyloxy)benzene, 1,4-bis[(2-ethyl-hexyl)oxy]-2,5-diiodobenzene, and 5,5?-diethynyl-2, 2?-bipyridine. Complexation studies involving these polymers and a variety of transition metals suggest that ligand exchange leads to three-dimensional networks, which feature BipyPPE-metal-BipyPPE cross-links and display interesting optoelectronic properties. It is found that complexes with group 12 d10 ions (Zn2+ and Cd2+) are emissive, while other transition metals such as Cu+, Co2+, and Ni 2+ form nonradiative metal-to-ligand charge-transfer complexes with the polymers.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.15862-18-7. In my other articles, you can also check out more blogs about 15862-18-7
