两种芴基ICT化合物的合成及光谱研究

Synthesis and spectral study of two ICT compound containing fluorene

咔唑经烷基化、酰化处理后与2-氨基芴、2,7-二氨基芴进行缩合反应,得到了两种ICT化合物9-乙基咔唑-3-亚甲基-芴-2-胺(简称ECzFA)和双(N-乙基咔唑-3-基)甲醛缩2,7-二氨基芴(简称BECzFA)。采用IR、1H NMR对其结构进行了表征,并对其荧光性质进行了初步研究。结果表明,这两种化合物均具有优良的电荷转移效果,且在溶剂中呈淡蓝色荧光(Em1max1=352 nm,Em2max1=367 nm)。这两种化合物有望在光电子集成、荧光探针和双光子吸收材料等领域得到应用。

Two intramolecular charge transfer compounds N-（（9-ethyl-9H-carbazol-3-yl） methylene）-9H- fluorene-2-amine （ECzFA） and N2, NT-bis （ （ 9-ethyl-9 H-carbazol-3-yl ） methylene ） -9H-fluorene-2,7-all- amine （ BEC zFA ） were synthesized from 9 H-fluorene-2-amine, 9 H-fluorene-2,7 -diamine and carbazole by the alkylation, acylation, condensation reactions. The structures of products were confirmed by IR and 1H NMR. Their fluorescence properties were examined preliminarily. The results showed that two compounds have excellent effects of charge-transfer and emitted the light blue fluorescence in the DMSO （Emlmax1 = 352 nm,Em2maxl = 367 nm）. The compounds were expected to a potential application use as photoelectron integration, fluorescence probe and two-photon absorption material.
