Novel narrow bandgap polymers from sp3 carbon-bridged bithienyls: poly(4,4-ethylenedioxy-4H-cyclopenta[2,1-b;3,4-b′]dithiophene)
Abstract
A hydrophilic conjugated polymer with a bandgap of 1.2 eV has been obtained by electropolymerization of 4,4-ethylenedioxy-4H-cyclopenta[2,1-b;3,4-b′]dithiophene.
