Influence of H-Bonding on Self Assembly and Tunable Dual-Emission of Carbazole-Based Zn(II)-Terpyridine Metallocycles

Recent Developments in the Preparation and Chemistry of Metallacycles and Metallacages via Coordination

“…Metallacycles constructed from substituted carbazole ligands terminating in two terpyridine donors and Zn­(II) ions were studied by Grimsdale and co-workers, with a focus on the effects of hydrogen bonding on assembly, and the tunable emission of the system (Figure ) . Two different ligands were made, a parent carbazole, and an N -alkylated carbazole containing a 12 carbon chain.…”

“…Assembly of a ditopic terpyridyl donor with Zn­(II) ions furnishes a pentagonal metallacycle with intraligand charge transfer bands as a kinetically stabilized self-assembly product. Adapted with permission from ref . Copyright 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.…”
