a Normalized phosphorescence spectra of EtCz in PVA film under ambient conditions (top) and in m-THF (1 × 10−5 M) at 77 K (bottom). b Phosphorescence lifetimes and efficiencies of CzA and EtCz in PVA films. c 1H NMR spectra of the emitters within/without PVA matrix at 293 K. d Partial NOESY NMR spectrum of CzA/PVA in DMSO-d6 at 293 K. e A conceivable mechanism for UOP of the emitters in PVA film.
