Abstract

Abstract : Reduced band gap materials via cyclopenta-fused polycyclic aromatic hydrocarbon inclusion in donor–acceptor copolymers. Abstract : A series of reduced band gap donor–acceptor copolymers that contain electron accepting 1, 2, 6, 7-tetra(4-dodecylphenyl)dicyclopenta[ cd, jk ]pyrene were prepared. The hydrocarbon acceptor relies on its cyclopenta-fused polycyclic aromatic hydrocarbon (CP-PAH) character to access a relatively reduced lowest unoccupied molecular orbital. The donor unit was varied between thiophene, bithiophene, and 1, 4-diethynyl-2, 5-bis(octyloxy)-benzene producing polymers with band gaps between 1.69–1.74 eV. The synthetic methodology as well as the optoelectronic properties of the donor–acceptor copolymers, including thin-film absorption and cyclic voltammetry, are presented.
