摘要:
Freshly developing lines of research in luminescent signalling with metal complexes over the last year are critically discussed. Metal-containing moieties are found to serve as remarkable lumophores with delayed emission and also as efficient receptors especially for anionic species. The photophysical concepts of metal-centred (MC) excited states, metal to ligand charge transfer (MLCT) excited states, metal-metal to ligand charge transfer (MMLCT) excited states, photoinduced electron transfer (PET) processes and electronic energy transfer (EET) processes are all being exploited during these signalling operations. Novel sensors and switches are emerging as a result. (C) 1999 Elsevier Science S.A. All rights reserved.
