Long-lived 3MLCT emission with high quantum yield from platinum(II) terpyridyl acetylide complexes in CH2Cl2 solution at room temperature has been observed.
Photoluminescence with high quantum yield and long lifetime froma triplet metal-to-ligand charge transfer (MLCT) excited state influid solution at room temperature has been observed for a seriesof platinum(II) 4‘-p-tolyl-terpyridyl acetylide complexes.
