【摘要】 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λmax分别位于330 nm和348 nm;在330 nm波长激发下,λem分别位于410 nm和425 nm。更多还原

【Abstract】 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 by1 H NMR,13 C NMR,IR and ESI-MS. The UV-Vis and FL spectroscopies of 4 were investigated. λmaxof 4a and 4b were 330 nm and 348 nm,and under excitation of 330 nm,λemwere 410 nm and 425 nm,respectively.更多还原
