Four styryl pyrazine derivatives with different structure have been synthesized. The absorption and fluorescence spectra of these compounds in solvents with different polarity were measured. According to the spectral data and the possible conformation of these compound in ground state, a conclusion on the favorable conformation for the fluorescence emission of these compounds was confirmed.

Key words: Styryl pyrazine, Molecular structure, Conformational equilibrium
