Abstract: The spectra of charge transfer complexes (CTC) of six fluorescent organic compounds, 1,4-bis (o-cyanostyryl) benzene, 1-(o-cyanostyryl)-4-(o-chlorostyryl) benzene,1,4-bis (o-chlorostyryl) benzene, 1,2-bis (5-methylbenzoxazol-2-yl) ethylene , 2,5-tris (5-ter-butylbenzoxazol-2-yl) thiophene, and 3-pheny-5,6-benzocoumarin with TCNE, DDQ,and TCNQ were determined spectrophotometrically.The ionization potentials (Ip) werecalculated and Ip (eV) of the donors are 7.94, 7.83, 7.81.8.37, 8.09, and 8.35 respectively,The relationship between Ip and v when TCNQ acted as arceptor was also inferred.Theemirical equation is following:Ip=2.48+3.37×10-4vTCNQ(cm)-1.
