英文摘要by using cyclopentadithiophene (cpdt) as an electron-rich unit, difluro-2,1,3-benzothiadiazole (dfbt), diketopyrrolopyrrole (dpp) and thienopyrroledione (tpd) as electron deficient units, two novel alternating conjugated copolymers with a d-a(1)-d-a(2) structure, pcpdt-dfbt-tpd and pcpdt-dfbt-dpp, were designed and synthesized. the incorporation of two electron-deficient units in the structure of terpolymer could enhance solubility, adjust band gap, optimize stack property, and change the electron distribution in the system. both the polymers pcpdt-dfbt-tpd and pcpdt-dfbt-dpp show highly solubility in o-dichlorobenzene, chlorobenzene, and o-xylene. optical bandgaps of these polymers can be estimated by extrapolating from the absorption edge of these films to be 1.56 ev for pcpdt-dfbt-tdp and 1.34 ev for pcpdt-dfbt-dpp. the power conversion efficiencies of 3.15 % for pcpdt-dfbt-tpd and 3.11 % for pcpdt-dfbt-dpp were achieved in a bulk heterojunction (bhj) photovoltaic device with a configuration of ito/pedot: pss/polymers: pc71bm/c-60-bis surfactant/ag under the illumination of am 1.5g at 100 ma cm(-2).
