Original Abstract

Two pyrrolo[3,4-c]pyrrole-1,4-diones (diketopyrrolopyrroles, DPP) with 4''-diphenylamino-stilben-4'-yl substituents at the 3- and 3,6-positions of the DPP heterocycle are synthesized. The 1H and 13C NMR spectra of their soluble derivatives, N(2) and N(5)-dialkylated by 2-ethylhexyl bromoacetate, were completely assigned. Soluble DPPs show photovoltaic activity in bulk heterojunction solar cells. Their electrochemistry and absorption and fluorescence spectra were studied.
