Mechanizm of biphenylene fluorescence
Abstract
It is shown that the S1↔S0 pure-electron transition frequencies of absorption and emission essentially differ. From this and known photophysical characteristics of biphenylene it follows that its fluorescence mechanism fits into model of specific C2v symmetrical cis-azoalkane fluorescence having exchange-resonant nature. The model explains the reasons for the unusual intensity, half-width, polarization, and predominant manifestation of completely symmetric vibrations in the fluorescence spectrum.
