Abstract  

A series of styryl pyrazine derivatives with different electron donating or withdrawing substituents were synthesized. The absorption and emission spectra of these compounds in different polar or viscous medium were obtained. Results indicate that cooperation of photo-isomerization and 'negative solvatokinetic' effect leads to lower fluorescence quantum yields of these compounds. Properties of substituents have great influence on the photophysical and photochendcal behavior of the synthesized pyrazine derivatives.
