Electronic Characterization of 1-Keto-4-Thioketo-3, 6-diphenylpyrrolo(3, 4-c) pyrrole

摘要

Electronic characterization of mono-keto-mono-thioketo-pyrrolopyrrole (MTPP) has been carried out in order to explore new electronic applications. The crystal structure of MTPP is found to be isomorphous with that of modification I of dithioketopyrrologyrrole (DTPP). The color is nearly between those of diketopyrrolopyrrole (DPP) and DTPP. The intermolecular hydrogen bonds based on both NH O and NH S are found to be considerably weak as compared with those of DPP (NH O) and DTPP (NH S). The absorption spectrum of MTPP suggests a potential application for LCD blue-filters.
