Both compounds can emit strong single-photon excited fluorescence (SPEF) and two-photon excited fluorescence (TPEF) with the emission peaks around ~560 nm and with the lifetime of ~1ns.展开更多
Two new compounds involving a thiophene moiety named as 2,5-bis[4-(N,N- diphenyl- amino)styryl]thiophene (BPST) and 2,5-bis[4-(N,N-diethylamino)styryl]thiophene (BEST) have been synthesized. The two-photon absorptio...Two new compounds involving a thiophene moiety named as 2,5-bis[4-(N,N- diphenyl- amino)styryl]thiophene (BPST) and 2,5-bis[4-(N,N-diethylamino)styryl]thiophene (BEST) have been synthesized. The two-photon absorption cross section of BPST was measured as large as 256 × 10-50 cm4·s/photon, when it was excited by 800 nm femtosecond laser.展开更多
