Organometallic complexes with 1,2,3-triazole-derived ligands
1,2,3-triazoles derived through copper(I) catalysed ‘click’ chemistry have received rapidly growing interest for their application in new ligand systems for transitions metal complexes. In addition to conventional N-donor coordination chemistry, 1,2,3-triazoles allow access to a rich diversity of organometallic ligands including cyclometalates, triazolide and triazolylidene NHC based ligands. Complexes of these ligand systems are being explored for their application in light emitting devices, solar energy conversion and as supporting ligands in novel catalytic complexes. This review serves to highlight some of the key developments in these areas.
