The present invention is to provide a photoelectric conversion element having excellent heat resistance. In addition, an imaging element and an optical sensor which include the photoelectric conversion element are provided. Furthermore, a compound applied to the photoelectric conversion element is provided. A photoelectric conversion element according to the present invention includes a conductive film, a photoelectric conversion film, and a transparent conductive film, in this order, in which the photoelectric conversion film contains a compound represented by Formula (1).
In Formula (1), Y1 represents a group represented by Formula (1-1) or a group represented by Formula (1-2).
chlorinated end groups is an efficient strategy for developing small molecule nonfullerene acceptors (NFAs) with narrow bandgaps. Previous studies on nonfullerene acceptors with chlorinated end groups mainly focus on the modulation of either heterohalogenated or monochlorinated end groups, and the structure–property relationships in a series of isomeric NFAs are poorly understood. In this work, three A–D–A
