Excited state dynamics of meso-Arylethynyl-substituted subporphyrins can be tuned by 4-substituent at the arylethynyl group and solvent polarity. In polar acetonitrile, phenylethynyl subporphyrin 1 exhibited enhanced fluorescence, while (4-dimethylaminophenyl)ethynyl subporphyrin 2 showed red-shifted fluorescence from its charge-separated state and (4-nitrophenyl)ethynyl subporphyrin 3 displayed efficient fluorescence quenching due to charge separation.
