Title
Aryl(hetaryl)pyrazolines as new photoacid generators for optical information recording
Abstract

•Pyrazolines undergo photodehydrogenation both in various solvents and polymer films.•Various halogenated compounds provide pyrazolines photodehydrogenation.•The first-order kinetics of this reaction has been found in solvents and polymer films.•Photoacidity of pyrazolines is used for Rhodamine dyes fluorescence activation.•Rhodamine activation conjugated with pyrazoline photo acidity can be used for optical memory.

Photodehydrogenation of aryl(hetaryl)pyrazolines in the presence of organohalogen compounds has been used for fluorescence activation of Rhodamine laser dyes both in organic solvents and in polymer films. The ability of aryl(hetaryl)pyrazolines as photoacids to generate a highly fluorescent Rhodamine dye can be used for optical information recording.
