Dopamine polymerization promoted by a catecholase biomimetic CuII(μ-OH)CuII complex containing a triazine-based ligand

Abstract

We describe herein the catecholase-like catalytic activity and dopamine polymerization by using a dinuclear [LCuII(μ-OH)2CuII](ClO4)2 (1) complex where L is the dinucleating triazine-based ligand 6-chloro-N2,N2,N4,N4-tetrakis(pyridin-2-ylmethyl)-1,3,5-triazine-2,4-diamine. The kinetic parameters (kcat = 0.318 s−1, KM = 1.6 × 10−3 mol L−1, and kcat/KM = 198.8 L s−1 mol−1), mechanistic insights into the oxidation of 3,5-di-tert-butyl catechol and early characterization of poly(dopamine) are presented.
