Abstract:Three novel rhenium N−heterocyclic carbene complexes, [Re]−NHC−1−3 ([Re] = fac−Re(CO)3Br), were synthesized and characterized using a range of spectroscopic techniques. Photophysical, electrochemical and spectroelectrochemical studies were carried out to probe the properties of these organometallic compounds. Re−NHC−1 and Re−NHC−2 bear a phenanthrene backbone on an imidazole (NHC) ring, coordinating to Re by both the carbene C and a pyridyl group attached to one of the imidazole nitrogen atoms. Re−NHC−2 differ… Show more
“…9,10 Many of them are very efficient electrocatalysts and photocatalysts. 10–14 They emit blue-green to red light in solution at room temperature 15–21 and have been proposed as efficient circularly polarized luminescence emitters. 22–24 According to Massi and co-workers, they exhibit a particular photochemical reactivity 15,16 and can be used as photoinitiators of polymerization upon visible light.…”
The tricarbonylrhenium complexes that incorporate a mesoionic carbene ligand represent an emerging and promising class of molecules, the solid-state optical properties of which have rarely been investigated. The aim of...
