Characterization of a non-aggregating silicon(IV) phthalocyanine in aqueous solution: toward red-light-driven photocatalysis based on earth-abundant materials.

Photophysical and photochemical characterization of a novel cationic silicon phthalocyanine with excellent water solubility properties is reported. The robust red-light responsive compound shows very attractive features as a sensitizer for reductive and oxidative quenching processes to trigger photocatalytic substrate conversion in aqueous solution.
