A coherent green fluorescence was obtained by butylation at the 2-position of panchromatic 2,3-diaryl-5,8-diarylquinoxalines[2]to give corresponding 2-butyl-2,3-diaryl-5,8- diaryl-1H-quinoxalines[3]. Full color quinoxaline derivatives[2] were prepared from electronic modification at either the 2,3- or 5,8-positions at the peripheral ArX group or X group (X=H, -OMe, -NPh 2, -NMe2, -NMePh) of the quinoxalines. 2-Butylation converted one imine unit of the pyrazine ring to an amine group, which effectively altered the electron donor and acceptor functions to produce a coherent green fluorescence.
