摘要: Abstract By comparing fluorescence behaviour of carbazole derivatives carb-N-R with R = phenyl (CB). 4-cyanophenyl (CBN). 1-naphthyl (CIN) and 9′-phenanthryl (C9P) theoretical presuppositions for efficient TICT state population are exemplified. While CB fluoresces from a locally excited state, CBN, CIN C9P exhibit exclusively in polar solvents, an unusually lugh quantum yield.
