Abstract

Condensation of 4-(3,5-diphenylpyrazol-1-yl)benzoyl chloride with hydrochlorides of ω-aminomethyl aryl ketones or aroyl hydrazines and subsequent cyclization of the condensation products in phosphorus oxychloride gave new effective luminophors. Their structure was confirmed by the data of IR and NMR spectroscopy. The influence of the structure of the molecules on the spectroluminescence characteristics was investigated. The high quantum yield of the photoluminescence and of the luminescence in the region of sensitivity of the photomultiplier, and the raised photostability and good solubility in aromatic hydrocarbons favored the application of the substances obtained in liquid scintillators.
