Tetrathiafulvalene Hybridized with Indacenetetraone as Visible-light-harvesting Electron Acceptor Applicable to Bulk-heterojunction Organic Photovoltaics
π-Extension of tetrathiafulvalene by hybridization with an indacenetetraone leads to an electron acceptor that can harvest visible light efficiently and serve as an electron-transport material for poly(3-hexylthiophene)-based bulk-heterojunction photovoltaics, where brief thermal annealing of the active layer results in better carrier transport pathways to enhance the device performance.
