A variety of new conjugated dyes bearing a benzophenone unit were synthesized, and the linear absorption and emission were determined. Two-photon absorption properties of the derivatives have been measured by a Ti:sapphire femtosecond laser tuning from 720 to 880 nm at intervals of 20 nm. One- and two-photon optical properties of the derivatives were found to be significantly dependent on their chemical structures.
