BODIPY-cucurbituril complexes: supramolecular approach toward improvement of photodynamic activity

Abstract

The host-guest interaction of cucurbit[7]uril with lipophilic BODIPYs decreases their aggregation in water and improves the photophysical properties. Phototoxicity of the complex with one CB[7] moiety increased up to seven times compared to that of the free photosensitizer. This supramolecular interaction is an efficient approach to increasing the photodynamic activity of BODIPY photosensitizers.
