제목 Synthesis and Photovoltaic Properties of New Donor-Acceptor Polymers Containing Benzothiophene as a Conjugated Side Chain on Benzodithiophene Unit.
초록 We have introduced 5-ethylhexyl benzo[b]thiophene as a conjugated side chain substituent on benzodithiophene (BDT) unit to attain new BDT based electron rich unit, where the benzo[b]thiophene is attached on both sides of the phenyl ring. An array of two donor-acceptor (D-A) polymers (P1, P2) based on new BDT moiety as electron rich unit and benzothiadiazole (BT) unit as electron deficient entity were designed and synthesized. The polymers exhibited good thermal stability and film forming ability. The absorption spectra of P1 and P2 showed broader absorption band from 300 to 800 nm with efficient intramolecular charge transfer. As these polymers possess good thermal properties, film forming nature and low bandgap, they appear to be interesting candidates for solar cell applications.
