Phosphorescence lifctim.?s for the ?I-alkyl benzenes are independent of the alkyl chain length for a gibe-en rigid glass at both liquid nitrogen and argon temperatures. AppxenUy, the lifetimes decrease only if branching occurs nt the alkyt arbor. attached to benzene. Various alkyl substituents seem
Delayed emission was observed for alternating and random copolymers of 9-phenanthrylmethyl methacrylate and 2-(9-carbazolyl)ethyl methacrylate with styrene in a rigid solution at 77 K. All the copolymers showed monomeric phosphorescence and delayed fluorescence, indicating the absence of deep trap s
