摘要

Polydibenzofurans of general formula IMAGE Oxidised polydibenzofurans of general formula IMAGE in which X is the anion of a supporting electrolyte ensuring electron neutrality, m does not exceed 2 and n is the degree of polymerisation. The oxidised and nonoxidised copolymers of dibenzofurans and crown ether DB18C6. Processes for their preparation by anodic electropolymerisation. Applications as modifiers for metal electrodes and as electrochromic materials. IMAGE
