Abstract
AbstractSummary: A novel acrylate polymer with a carbazole pendant group and bipyridine derivatives as side chains was synthesized, in which derivatives of bipyridine as electro‐optic chromophores and carbazole as photoconductive moiety were covalently linked to the acrylate backbone. 2–(Carbazol‐9‐yl)ethyl methacrylate (CEM) and methacrylic 2‐[5‐(2‐{5,5′‐dimethyl‐6′‐[2‐(5‐pentylthiophen‐2‐yl)vinyl]‐3,3′‐bipyridin‐6‐yl}vinyl)thiophen‐2‐yl]ethyl methacrylate (BiPy) were synthesized and then copolymerized to give 99:1, 98:2, 92:8 (mol/mol) CEM/BiPy copolymers. Films of the copolymers blended with poly(3‐octylthiophene) (P3OT) or poly(3‐decylthiophene) (PDT) and sandwiched between the transparent ITO and Al electrode were examined for photovoltaic properties.
