New composite materials derived from a porous luminescent zinc-containing coordination polymer and organic dyes, namely, 5-(4-diethylamino)benzylidene)pyrimidine-2,4,6(1H,3H,5H)-trione (KR) and methylene blue (MB) have been prepared. Upon excitation of the polymer matrix, the composite with KR was shown to display dual luminescence attributed to energy transfer between the luminophores, while there is no such transfer in the composite with MB. The ratio of the emission intensities of the inorganic and organic constituents of the composite films in liquid hydrocarbons was shown to depend on the hydrocarbon structure. Nitrobenzene vapor selectively quenches the luminescence of the coordination polymer in these composites, which suggests that the dye can be used as an internal standard in luminescent analytical measurements.

芳香族和脂肪族烃对含锌配位聚合物和染料衍生的复合材料的光谱和发光性能的影响

源自多孔发光含锌配位聚合物和有机染料的新型复合材料，即 5-(4-diethylamino)benzlidene)pyrimidine-2,4,6(1H,3H,5H)-trione (KR) 和亚甲蓝(MB) 已经准备好了。在聚合物基体的激发下，具有 KR 的复合材料显示出归因于发光体之间能量转移的双重发光，而在具有 MB 的复合材料中没有这种转移。液态烃中复合膜的无机和有机成分的发射强度之比取决于烃结构。硝基苯蒸气选择性地淬灭这些复合材料中配位聚合物的发光，这表明该染料可用作发光分析测量中的内标。
