제목 Conjugated Polymers Consisting of Dibenzosilole and Quinoxaline with Coplanar Properties
초록 Over the past few years, Donor-Acceptor (D-A) type low-band gap polymers have drawn great attention, as their electronic properties can be easily be changed based on the unique combination of the D-A unit. These polymers can also exhibit broader absorption spectra to longer wavelengths compared to more traditional polymers. In this study, two new D-A type polymers, poly(dibenzosilole-diphenylquinoxaline) (PSiPDTQ) and poly(dibenzosilole-dibenzophenazine) (PSiFDTQ), in which dibenzosilole derivatives were introduced as a donor, were successfully polymerized. Compared with PSiPDTQ, a more effective π-π interaction is expected in PSiFDTQ because of the superior coplanarity properties of the fused-phenyl rings, which enables a high FF in OPVs.
