摘要：

以N-乙基咔唑为原料，通过室温固相化学反应改进合成了2种双光子吸收材料(咔唑类衍生物2, 8-二[2'-(吡啶-4"-基)乙烯基]-5-乙基咔唑(L1)，2, 8-二[2'-(吡啶-2"-基)乙烯基]-5-乙基咔唑(L2)，其结构经1H NMR，IR和MS确证，利用Z-扫描技术，测试了其纳秒下的双光子吸收截面为6 210和5 590 GM (1 GM = 1   ´ 10 -50 cm 4 · s · photon -1 )，用820 nm的飞秒单脉冲激光作为写入激光对存储介质进行双光子光漂白，对其作为三维光存储材料作了初步的探索。

关键词: Ｎ-乙基咔唑，吡啶乙烯基衍生物，固相反应，双光子吸收，光漂白存储

Abstract:

2,8-Bis[2'-(4"-pyridyl)ethenyl]-5-ethylcarbazole (L1) and 2,8-bis[2'-(2"- pyridyl)ethenyl]-5-ethylcarbazole (L2) were synthesized by solid-state reaction at room temperature from N-ethyl carbazole. 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 Write laser was applied to the storage medium for two-photon photobleaching, indicating they would be three-dimensional optical storage materials.

Key words: N-ethyl carbazole, vinyl pyridine derivative, solid-state reaction, two-photon absorption, photobleaching storage
