Two new D-π-A type compounds, where electron-donor D is tertiary amino group, electron-acceptor A is 2-benzothiazolyl and π is two conjugated styryl units, have been synthesized.They are named as trans, trans-2-{4-[4-(N, N-diethylamino)styryl]styryl}-1, 3-benzothiazole and trans, trans-2-{4-[4-(N, N-diphenylamino)styryl]styryl}-1, 3-benzothiazole.Both compounds show strong two-photon excited fluorescence in yellow-orange region when excited by a femtosecond laser at 800 nm.
