Abstract

Hexa-peri-hexabenzocoronene (HBC) is a discotic polycyclic aromatic hydrocarbon with good charge transport characteristics while the light harvesting property of porphyrins is well-known. In order to take advantage of the properties of both materials, a porphyrin-hexa-peri-hexabenzocoronene-porphyrin triad 6 was synthesised for the first time. In photoluminescence studies, the emission from the higher energy HBC unit was completely quenched by the porphyrin unit indicating efficient energy transfer. This novel hybrid material 6 was tested in bulk heterojunction photovoltaic devices reaching a power conversion efficiency of 1.2%.
