Benzotriazole-Based Donor-Acceptor Type Semiconducting Polymers for Photovoltaic Devices |
초록 |
A series of low band gap polymers composed of benzotriazole and benzo[1,2-b:4,5-b']dithiophene (BDT) derivatives were synthesized using a Stille cross-coupling ewaction for use in organic photovoltaic devices. Linear or branched alkyl groups were incoporated into the benzotriazole-based accepting monomer part, and alkoxy or alkylthiophene groups were introduced to BDT-based donating monomer part. Changes in photo-pysical properties of the polymers by the structural modification of the donor-acceptor type low band gap polymers were inverstigated. The optical band gap energies of the polymers were measured to be 2.03-1.90 eV depending on the polymer structure. Solution-processed field-effect transistors were fabricated and characterized using the polymers as p-type channel materials. Bulk hetero-junction photovoltaic devices were fabricated using the polymers with PC71BM as the electron acceptor. |
