DOI: 10.1021/acsomega.5c10321
Abstract: We report the synthesis and characterization of a new series of imidazopyridine-based N-heterocyclic carbene (NHC) ligands, including three unique binding modes: less atom-stabilized (C5-bound), remote normal (C7-bound), and remote mesoionic (C8-bound) configurations. These distinct ligands… read more here.

DOI: 10.1021/jacs.4c01138
Abstract: A new class of photoswitchable NHC ligands, named azImBA, has been developed by integrating azobenzene into a previously unreported imidazobenzoxazol-1-ylidene framework. These rigid photochromic carbenes enable precise control over confinement around a metal's coordination sphere.… read more here.
