Abstract

2,2′-biquinoxyalyl and thieno[2,3-b:4,5-b′]biquinoxyalyl can be photoreduced in acidified alcoholic solutions and in aqueous solutions of acids. Quantum yields of the photochemical reaction have been determined. The fluorescence and phosphorescence spectra of these compounds have been recorded and the fluorescence quantum yields have been determined. A mechanism of the photoreduction has been proposed.

Zusammenfassung

2,2′-Bichinoxalyl und Thieno[2,3-b:4,5-b′]bichinoxalyl unterliegen photochemischer Reaktion in angesäuerten Alkohollösungen und in wäßrigen Säurelösungen. Es wurde die photochemische Quantenausbeute bestimmt. Außerdem wurden die Fluoreszenz- und Phosphoreszenz-Spektren aufgezeichnet und die Fluoreszenz-Quantenausbeuten bestimmt. Zugleich wurde ein Mechanismus zur Photoreduktion vorgeschlagen.
