| 摘 要： | When certain lasers are used as pump source, some organic molecules can simultaneously absorb two photons to reach one of their excited states and subsequently frequency up-converted fluorescence emission may follow1,2. Compared with common single-photon excited fluorescence (SPEF), this two-photon excited fluorescence (TPEF) is characterized by its excitation process of two-photon absorption (TPA) that presents several advantages including high three-dimensional resolution as well as low…

| Abstract: | Two new D--A type compounds, where electron-donor D is tertiary amino group, electron-acceptor A is 2-benzothiazolyl and ?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. |
