โฆ Synopsis
Intermolcsular charge-trnnsfer phosphorescence and fluorescence were observed for the biphenyl single crystal containing 1, 2,4,5tetracyanobenzcne as a guest. In addition, the delayed cliarge-transfer fluorescence due to triplcttrip!et annihilation wns observed for the first time.

The temperature dependence of emission spectra and their decay parameters for pyromellitic dianhydride-phenanthrene chargetransfer crystals have been investigated between 1.7 and 300 K. It has been established that the delayed fluorescence originates from triplet-triplet annihilation at temperatures
