Porphyrin is a tetrapyrrolic macrocycle with complete conjugation in which four pyrroles are interconnected by four methine bridges (meso-positions). In contrast, corrole is an analogue of porphyrin with three meso-positions and one direct pyrrole-pyrrole linkage. During doctoral studies, meso-meso directly linked corrole-porphyrin-corrole (C-P-C) and porphyrin-corrole-porphyrin (P-C-P) hybrids had been synthesized for the first time and their coordination chemistry was highly explored.

Carbaporphyrin is another analogue of porphyrin with one or more pyrrolic nitrogen atoms replaced by carbon atoms. The incorporation of carbon atoms into the core of the macrocycle makes it a promising ligand to a) stabilize organometallic complexes and b) study metal-arene interactions. In postdoctoral work, research has been focused on syntheses, structures, and coordination chemistry of biphenyl- and bipyricorrole. Overall, I have a great deal of expertise in coordination chemistry and photophysical properties of organic π-conjugated macrocycles.
