Non fullerene based acceptor compound containing benzoselenadiazole and organic photovoltaic device including the same

摘要

Problem to be solved: to provide an organic photoelectric element such as an opfullerene based acceptor compound containing benzenselenadiazole having a suitable absorption wavelength region and photoelectric conversion efficiency, and OPD or OPV including the same.The non fullerene acceptor compound containing benzoselenadiazole has the following formula.AR1 is a hetero five membered ring, and ar2 is a monocyclic or polycyclic heteroaromatic ring derivative of C5-C20, and PI is a monocyclic or polycyclic heterocyclic ring derivative of C5-C20 and M = 0 to Eg is a monocyclic or polycyclic derivative containing ketone groups and electron withdrawing groups.1Diagram
