Research Interests

Professor Chmielewski was one of the main contributors to the investigations of coordination chemistry of mono- and diheteroporphyrins, especially with nickel. He also worked on the coordination chemistry of N-alkylporphyrins and reactivity of porphyrin cation radicals.

His major achievement is the synthesis of inverted porphyrin (published 1994) which subsequently yielded a series of papers describing its reactivity and coordinating properties.

At present prof. Chmielewski continues his research independently. He uses inverted porphyrin to construct supramolecular assemblies.
