Synthesis and characterisation of main-chain oligomeric cyclopalladated azobenzene complexes

摘要

In this paper we report the synthesis of main-chain oligomeric cyclopalladated azobenzene complexes. The approach we followed was focused on the synthesis of difunctional azo-ligands substituted properly with terminal polymerisable OH groups, synthesis of cyclopalladated monomers and polycondensation reaction with acid chlorides as comonomers. In this way, using the interfacial method, two soluble cyclopalladated oligomers P1 and P2 were synthesised.
