Investigate how systematic substitutions at the gamma and delta carbon positions influence triplet state reactivity and Type II photoprocesses in phenyl ketones.
Synthesized and characterized a series of phenyl ketone derivatives containing various gamma and delta substituents.
Conducted photochemical irradiation experiments to monitor triplet decay kinetics, quantum yields, and photochemical cleavage rates.
Substituents at the gamma position significantly alter the rate of intramolecular hydrogen abstraction from the excited triplet state.
Modifications at the delta position influence triplet state lifetimes and modulate competing non-radiative decay mechanisms.
