Organic phototransistors based on high-quality 2,8-dichloro-5,11-dihexyl-indolo[3,2-b]carbazo (CHICZ) single crystals show the highest photoresponsivity of 3x10(3) A W-1, photosensitivity of 2x10(4) and the detectivity can achieve 8.4x10(14) Jones. We also discovered good linear dependence of log( photosensitivity) versus the wavelength when the devices were illuminated with a series of same-intensity but different-wavelength lights. The organic phototransistors based on CHICZ single crystal have potential applications in wavelength-detection.
