合成了1,10-邻菲罗啉-5,6-二酮,利用IR,UV,~1 H NMR,MS和元素分析确认其结构,测定了1,10-邻菲罗啉-5,6-二酮的低温磷光光谱.实验结果表明:1,10-邻菲罗啉-5,6-二酮对紫外光有较强的吸收能力,其三重态能级约为18620cm^(-1),明显高于Eu^(3+)离子的受激发态能级,因此可预测1,10-邻菲罗啉-5,6-二酮可有效敏化Eu^(3+)离子的发光,有望用于制备单核或多核稀土配合物发光材料.
Novel 1,3-dioxolane C-nucleoside analogues of tiazofurin 2-(2-hydroxymethyl-1,3-dioxolan-4-yl)-1,3-thiazole- 4-carboxamide as well as N-nucleoside analogues of substituted imidazoles 1-(2-hydroxymethyl-1,3-dioxolan- 4-yl)-4-nitroimidazole and 1-(2-hydroxymethyl-1,3-dioxolan-4-yl)-4,5-dicyanoimidazole were synthesized from methyl acrylate through a multistep procedure. Their structures were confirmed by IR, 1H NMR, 13C NMR spectra and elemental analysis.
