Paper Abstract

The photoluminescence of three complexes of the type Zn(s-benzenethio1)2(2,9- dimethy1-1,10-phenanthroline) [s = F5, H, 4-MeO) has been investigated in EtOH glasses from 4.3 to 75 K. The pentafluoro molecule exhibits only inn* emission characteristic of the heterocyclic ligand, the methoxy compound displays a unique charge-transfer emission, but the unsubstituted complex displays both types of luminescence bands. The results are interpreted in terms of a barrier to energy migration in individual molecules that is a consequence of the near-degeneracy of two electronic configurations of widely disparate characteristics.
