제목 Synthesis and characterization of A-D-A small molecules dyes based on chromone malononitrile as the acceptor moiety
초록 New A-D-A small molecule dyes, denoted as IDTT-OX and IDTT-EPMP-IDC have been successfully synthesized as donor material for bulk heterojunction organic solar cells (OSCs). These dyes contain indacedithieno[3,2-b]thiophene (IDTT) as the donor moiety, while phenylisoxazolone (OX) or malononitrile derivatives (EPMP-IDC) are the acceptor units. IDTT-OX exhibits a strong self-aggregation behavior and broad absorption with an optical band gap of 1.88 eV. While IDTT-EPMP-IDC shows different behavior, the self-aggregation of IDTT-EPMP was efficiently restricted by the presence of the alkyl group at EPMP-IDC functional group in the molecule and it has 1.60 eV optical bandgap. The inverted-type OSCs based on the blend of IDTT-OX (or IDTT-EPMP-IDC) as a donor, PC71BM as an acceptor are fabricated. The power conversion efficiencies (PCEs) of the optimized OSCs reached up to 0.29% for IDTT-OX and 2.07% for IDTT-EPMP-IDC.
