Highly Efficient Ir(III)-Coumarin Photo-Redox Catalyst for Synergetic Multi-Mode Cancer Photo-Therapy

Synthesis and photophysical properties of iridium(III) bisterpyridine and its homologues: A family of complexes with a long-lived excited state

A new synthetic procedure has been developed which makes possible the preparation of IrLL′3+ complexes (L, L′ = terpyridine derivative) in good yields. In a first step, IrLCl3 is obtained under relatively mild conditions as an intermediate. Subsequent reaction with L′ (a few minutes in refluxing ethylene glycol) affords IrLL′3+. The electrochemical behavior and ground- and excited-state spectroscopic properties of four IrLL′3+ complexes in nitrile solvents are reported. The X-ray structure of one of these complexes is also described. The complexes have been designed keeping in mind their incorporation in linearly arranged multicomponent arrays, according to a templating strategy based on the assembly of tpy-type ligands by the Ir(III) center. The complexes feature a high-lying level for the luminescent excited state (>2.5 eV), with a satisfactory room-temperature luminescence intensity (φem ≈ 10-2) and lifetime on the microsecond time scale. These favorable properties indicate that the Ir(III)-tpy center will not be the final recipient of the energy-harvesting processes in multipartite systems built around them. Temperature-dependent studies of the luminescence properties in the 95-298 K range indicate that the higher-lying levels of these complexes are not efficient pathways for deactivation of the luminescent states. For these reasons, it is concluded that the studied Ir-tpy-type complexes are well suited (i) to play the role of photoactive center and to gather photo- and electroactive units or (ii) to act as electron relays in linearly arranged multicomponent arrays.
