A new bithiophene-based organic luminescence material, named 5,5'-bis(4-N-carbazoylstyryl)-2,2'-bithiophene (BCSBT), was synthesized. Its single-photon excited fluorescence band is located in the range of 520-530 nm, witha quantum yield of around 10 %. The compound emits strong two-photon-excited fluorescence when excited by 200 fs laser pulses. The two-photon absorption cross section of BCSBT was found to be 124×10 - 5 0 cm 4 s by the two-photon-excited fluorescence method.
