Abstract

It is confirmed by measurements of fluorescence spectra and quantum yields that the fluorescence in tolan originates from the same state that causes the absorption band at lowest energy. The temp. dependence of the fluorescence quantum yield shows that this state is thermally deactivated with an activation energy of EA = 14.0 kJ/mol. Geometry optimizations of the states S0, S1, and T1 of tolane ...
