Two new compounds involving a thiophene moiety named as 2,5-bis [4-(N,N- diphenylamino) 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.
- Thiophene,
- two-photon absorption,
- two-photon excited fluorescence.
