Abstract    Photoluminescent and biocompatible tricarbonylrhenium(I) complexes find a variety of applications as imaging agents . Some of them show photochemical reactivity and are potentially usable in the fields of carbon monoxide-based phototherapy and dynamic phototherapy of tumor cells . We show here how the properties of these versatile compounds may strongly vary when adapting the choice of their constituting ligands within the same family. Our team has recently developed an original family of air- and water stable complexes incorporating a pyridyl-triazole (pyta) ligand coupled with a phenylbenzoxazole (PBO) moiety. Complexes bearing a chloride ligand displayed very high lightfastness. Remarkably, some of them showed strong solid-state luminescence enhancement (SLE), with photoluminescence quantum yield as high as 55% . This effect was accompanied by an unprecedented sensitivity to mechanical stimuli. An original photophysical mechanism was proposed to explain this phenomenon . Some structural odifications of the organic ligand were then carried out to facilitate the synthetic process while enhancing the spectroscopic properties. Furthermore, changing the chloride ligand by a triphenylphosphine unit endowed the complexes with photochemical reactivity. In solution, upon irradiation, easy substitution of one carbon monoxide (CO) by a solvent molecule occurred. With a reaction quantum yield close to 30% in deaerated acetonitrile, one of these complexes appeared as a promising photochemically CO-releasing molecule (PhotoCORM).This study paves the way for a new generation of efficient photoactive Re complexes, which could lead to attractive materials for optics and phototherapy.
