新型吲哚衍生物的合成及其光学性质

以吲哚为原料，经Vilsmeier-Haack, Ullmannhe和Witting-Hornor反应合成了两个新型的含吲哚环共轭化合物--1,4-二(3-苯乙烯基吲哚基)苯（4a）和1,4-二(3-萘乙烯基吲哚基)苯（4b），其结构经¹H NMR， ¹³C NMR， IR和ESI-MS表征。光学性能研究结果表明，4a和4b的λ_max分别位于330 nm和348 nm；在330 nm波长激发下，λ_em分别位于410 nm和425 nm。

Synthesis and Optical Properties of Novel Indole Derivatives

Two novel conjugated compounds containing indole ring, 1,4-bis-(3-styryl-1H-indolyl)benzene(4a) and 1,4-bis｛3-［2-(naphthalene-1-yl)vinyl］-1H-indol-1-yl｝benzene(4b) , were synthesized by Vilsmeier-Haack, Ullmannhe and Witting-Hornor reactions using indole as the starting material. The structures were characterized by ¹H NMR， ¹³C NMR， IR and ESI-MS. The UV-Vis and FL spectroscopies of 4 were investigated. λ_max of 4a and 4b were 330 nm and 348 nm, and under excitation of 330 nm, λ_em were 410 nm and 425 nm, respectively.
