Abstract:
1. An organic semiconductor device, comprising at least one semiconductor layer, and having light absorption performance in an infrared region, wherein the semiconductor layer contains a neutral radical compound of a trioxotriangulene (TOT) derivative that is shown in Chemical Formula (1) below as a semiconductor material: (In the above formula, “R” indicates a monovalent group), wherein an energy gap between a singly occupied molecular orbital and a lowest unoccupied molecular orbital of the neutral radical compound of Chemical Formula (1) is in a range of 0.1 to 1.0 eV, and wherein infrared radiation passing through the semiconductor layer is absorbed and converted to an electric current, wherein the neutral radical compound of Chemical Formula (1) has the monovalent group R being a monovalent functional group selected from the group consisting of a proton, a methyl group, an ethyl group, an n-propyl group, an isopropyl group, an n-butyl group, a t-butyl group, a cyclohexyl group, a 2,2,2-trifluoroethyl group, a pentafluoroethyl group, a heptafluoroisopropyl group, a phenyl group, a 4-methoxyphenyl group, a pentafluorophenyl group, a naphthyl group, a benzyl group, a methoxy group, an ethoxy group, an n-butoxy group, a t-butoxy group, a phenyloxy group, an amino group, a dimethylamino group, a diethylamino group, an isopropylamino group, a carboxyl group, a methoxycarbonyl group, an ethoxycarbonyl group, an isopropoxycarbonyl group, a t-butoxycarbonyl group, a trifluoromethoxycarbonyl group, a cyano group, a nitrile group, and halogens.
