Reversible modulation of redox states by photoexcitation provides a promising principle for creation of catalysts and sensors. The photoredox function can be uniquely executed by employing cyclometalated complexes of Ir(III) and Pt(II), as they possess long-lived triplet excited states. Studies, including organic/organometallic syntheses, photophysical characterization, electrochemical measurements, and DFT/TDDFT calculations, have established key strategies for the precise control of the excited-state redox processes. Key accomplishments include photocatalytic processes with quantum yields that exceed 100%, and phosphorescence bioprobes capable of producing turn-on responses in the thermodynamically challenging red emission regions. |
