The elusive phosphorescence of pyrromethene–BF2 dyes revealed in new multicomponent species containing Ru(ii)–terpyridine subunits
Abstract
The triplet emitting state of an indacene at 774 nm (of 50 ms life-time) was observed for the first time in new ruthenium(II) complexes based on bipartite ligands carrying one or two indacene subunits linked via phenylethynyl connectors to terpyridine fragments.
