Abstract

Isomeric orange-red luminescing substances containing a pyrazoline ring and a 1, 8-naphthoylene-1′,2′-benzimidazole grouping have been synthesized. An investigation of the UV absorption spectra, luminescence spectra, and IR spectra of the individual isomers has shown the desirability of separating the mixture of them formed in the synthetic process.
