In this study, the novel blue-light emitting materials based on polysubstituted benzodithiophene dervatives were prepared by utilizing the characteristics of the hetero atoms, and the white-light emitting organic EL devices using these compounds were fabricated. We have developed efficient synthetic methods of these luminescent materials. The various physical properties of these compounds have been measured, and the mechanisms of white-light emission obtained from the EL devices using these compounds were also examined.
