摘要： It is provided that an organic photodetector that exhibits high conversion efficiency. An organic photodetector comprising a structure in which a base material, a cathode, an active layer, and an anode are disposed in order, respectively, wherein the active layer includes a polymer compound having a benzo(bis)thiazole structural unit represented by chemical formula (1),




[in formula (1), T1 and T2 each independently represent an alkoxy group, a thioalkoxy group, a thiophene ring that is optionally substituted with a hydrocarbon group or an organosilyl group, a thiazole ring that is optionally substituted with a hydrocarbon group or an organosilyl group, or a phenyl group that is optionally substituted with a hydrocarbon group, an alkoxy group, a thioalkoxy group, an organosilyl group, a halogen atom, or a trifluoromethyl group, and B1 and B2 each represent a thiophene ring that is optionally substituted with a hydrocarbon group, a thiazole ring that is optionally substituted with a hydrocarbon group, or an ethynylene group.].

摘要： The present invention provides a transistor-based polyamine sensor with which it is possible to detect a polyamine easily and with high sensitivity. Specifically, the present invention provides a transistor-based polyamine sensor comprising a detection site, wherein an organic compound containing a carboxy group and a thiol group is immobilized on all or part of the surface of the detection site via the thiol group of the organic compound, a heavy metal ion is bound to the carboxy group of the organic compound, and a change in threshold voltage caused by bonding of the heavy metal ion to a polyamine is measured to detect the polyamine.
