Etin Köprülü İkili ve Üçlü Porfirin-Korol Hibrit Bileşiklerinin Sentezi ve Karakterizasyonu

Abstract

In recent years, increasing environmental problems result with high demands towards clean and renewable energy sources, hence solar energy as an energy resource and artificial photosynthesis have begun to be spotlight. The compounds obtained by combining porphyrin and the reduced porphyrin compound corrole in a single structure by using bridge formations are very important because these structures take role of donor-acceptor for energy transfer in mimicking photosynthesis studies and they are prefered as dye material in the third generation solar cells.

In the first part of the thesis, synthesis of ethynyl substituted porphyrin compounds and p-bromo phenyl substituted corrole compound are carried out. Then dyad porphyrin-corrole and triad corrole-porphyrin-corrole structures with ethyne bridges in meso-meso positions are synthesized by Sonogashira cross-coupling reaction.

In the second part of the thesis, structures of dyads and triads are identified by spectroscopic techniques and porphyrin macrocycle is determined as energy donor group, while corrole acts as a energy acceptor in these structures.
