Abstract

Abstract:

The topological structure of metallopolymers is one of the important reasons affecting their photoelectric properties. By introducing vinyl or alkynyl groups on different sites of the pyridine ligand， pyridine-ruthenium metallopolymers with different topological structures are prepared on the electrode surface by electrochemical polymerization. Additionally， UV-visible absorption spectra， infrared reflection spectra， scanning electron microscopy and electrochemical techniques are used to characterize the properties and morphologies of the above metallopolymers. The results show that the monomers with different topological structures exhibit different polymerization efficiency due to the effect of steric hindrance， and their polymerization products have obvious differences in photoelectric properties.
