FUSING PORPHYRINS WITH POLYCYCLIC AROMATIC HYDROCARBONS AND HETEROCYCLES FOR OPTOELECTRIC APPLICATIONS

摘要

A compound that can be used as a donor material in organic photovoltaic devices comprising a non-activated porphyrin fused with one or more non-activated polycyclic aromatic rings or one or more non-activated heterocyclic rings can be obtained by a thermal fusion process. By heating the reaction mixture of non-activated porphyrins with non-activated polycyclic aromatic rings or heterocyclic rings to a fusion temperature and holding for a predetermined time, fusion of one or more polycyciic rings or heterocyclic rings to the non-activated porphyrin core in meso,ß fashion is achieved resulting in hybrid structures containing a distorted porphyrin ring with annulated aromatic rings. The porphyrin core can be olygoporphyrins.
