研究開始時の研究の概要

Electron deficient porous porphyrin solids will be prepared and their properties investigated for photochemical purposes (singlet oxygen photosensitization), in the first instance. Depending on porosity and connectivity, the materials will be prepared using coordination chemistry (traditional MOF), polymer chemistry (networks) or supramolecular chemistry. Catalytic/sensing properties and separations will be investigated using the materials.

研究実績の概要

Compounds based on oxidized porphyrins were prepared and tested for their action for the photochemical generation of singlet oxygen. The materials were then utilized for oxidation of organic substrate and tested for use as antimicrobial materials.
The zirconium-based porous coordination polymers were prepared and were found to generate singlet oxygen with good efficiency. These materials were then used to oxidize small organic molecules as models for pharmaceutical intermediates or toxic materials. This work was published.
Another class of porous polymers was prepared and those materials were found to promote oxidation of the model substrate with better selectivity for mild oixidation. Other macrocycles were also tested for singlet oxygen generation.
