Abstract: The 4H-cyclopenta[2,1-b:3,4-b’]dithiophene (CPDT)-based conjugated polymers (CPs) have garnered significant attention in various fields of organic electronics due to their strong electron-donating properties, extended π-plane, and rigid, planar chemical structure. These unique features enable CPDT-based CPs to be highly advantageous for use in a range of organic semiconductor devices. While CPDT-based CPs have been extensively investigated and... More

Abstract: Benzo[1,2-d:4,5-d’]bis(oxazole) (BBO) is a conjugated building block that can be easily synthesized for the development of organic optoelectronic polymers. Here, the authors synthesized BBO-based polymers, P1 and P2, by coupling BBO with thiophenes for use in organic photodetectors (OPDs). The optical characteristics of P1 and P2 make them suitable for OPDs, as they selectively absorb the green light with a narrow bandwidth in the range of... More
