摘要

The title compound(BP-DPP), known as a red pigment as well as a photoconductor for photoeceptors, is characterized by an extremely large bathochromic shift upon crystallization, as compare with other DPP analogues. The electronic structure of BP- DPP has therefore been investigated from the standpoint of crystal structure and exciton coupling effects. BP-DPP is found to Crystallize in the bricks in a brick wall" fashion, just like J-aggregates in cyanine dyestuffs. On the molecular plane of BP- DPP, There are chains of intermolecular hydrogen bonds between the NH groups of one molecule and the O atom of neighboring one.
