METHOD FOR THE TERMINAL FUNCTIONALIZATION OF POLYALKYLTHIOPHENE BY USING A CLICK CHEMISTRY REACTION

摘要

invention polyalkyl thiophene according to the method of terminal functionalized, 1) to formula (1) as shown that 2-bromo-3-functionalized thiophene monomer lithium diisopropyl amide (LDA, Lithium diisopropylamide), zinc chloride (ZnCl ₂ ) and [1,3- ( ) ] ( )([1,3-bis(diphenylphosphino) propane] dichloronickel ( ), Ni (dppp) Cl ₂ ) and a polymerization catalyst system consisting of, as a polymerization terminator to the reaction and nyadeu (grignard) draw reagent represented by the formula (2) Molecular weight distribution is from 1.0 to 1.3 and having a molecular weight distribution of the symmetry, the step of preparing the polyalkyl thiophene (polyalkylthiophene) alkynyl group introduced to the terminal thereof represented by the formula (3); And 2) clicking the polyalkyl thiophene of the formula (3) chemical (click chemistry) with the reaction of copper / amine catalyst under the existence of a functional group introduced at the terminal is reacted with an azide compound of the formula (4) represented by the formula (5) which comprises the steps of preparing a poly-alkylthiophene: ; CH C-MgBr ;N3-R2; in ; The equations, ; R ₁ is an alkyl group of C1 ~ 12, ; R ₂ is a halogen atom, C1 ~ 50 alkyl group, a vinyl group, an alkyl, a hydroxyl group, a hydroxyl group, an alkyl aryl, an aryl hydroxyl, alkyl carboxyl, aryl carboxyl, alkyl aryl carboxyl group, an alkyl ester, aryl ester, aryl-alkyl ester group, a haloalkyl group, a haloaryl group, a halo-alkylaryl group, a nitro group, an aryl group, a nitro, an alkyl aryl nitro group, an alkyl amide group, aryl amide group, alkylaryl amide group, a cyano group, a cyano group or cyanoalkyl Noah aryl group, wherein when the terminal is used for all of the oligomer or polymer with azide R ₂ is the form of an oligomer or polymer thereof have, ; n is an integer from 10 to 100,000 monomer as a polymerization degree of polythiophene.
