2,8 -Bis [ 2'- ( 4"-pyridyl) ethenyl ] -5-ethylcarbazole and 2,8-bis [ 2'-(2"-pyridyl) ethenyl ] -5-ethyl-carbazole were synthesized from N-ethyl carbazole at room temperature via a solid-state reaction. Their structures were characterized by ~1H NMR, IR and MS. Two-photon absorption cross-sections were obtained by Z-scan technique. The femtosecond single pulse laser (820 nm) as writing laser was applied to the storage medium for two-photon photobleaching, indicating that they would be three-dimensional optical storage materials.
