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

We describe herein the catecholase-like catalytic activity and dopamine polymerization by using a dinuclear [LCu (μ-OH) Cu ](ClO ) (1) complex where L is the dinucleating triazine-based ligand 6-chloro-N ,N ,N ,N -tetrakis(pyridin-2-ylmethyl)-1,3,5-triazine-2,4-diamine. The kinetic parameters (k = 0...

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