中文摘要: 以丙烯酰胺为功能单体、乙二醇二甲基丙烯酸酯为交联剂 ,在聚合之前的溶液体系中均匀混入荧光分子姜黄素 ,制备了具有光致发光性能的块状聚合物 ,并将此聚合物粉碎为 4 0~ 75 μm直径的粉末。姜黄素在此聚合物中与其在乙醇溶液中相比 ,其荧光发射光谱有明显的蓝移现象。用同样方法制备的含有罗丹明 6G、四碘荧光素、荧光桃红的丙烯酰胺聚合物也有类似的现象 ,初步认为此蓝移现象的机理可能是聚合物的三维空间网状结构对于荧光分子的隔离效应导致其接近于单分子发光所致
英文摘要: A photoluminescence polymer was prepared using acrylamide as a monomer, a large excess of ethyleneglycol dimethacrylate as the cross-linking agent, and curcumin as a fluorescence additive. The polymer was ground into powder and screened in order to get even powder, whose diameter was from 40 to 75 microm. The emission spectra of curcumin in solid powder polymer show a strong blue shift compared with that of curcumin in C2H5OH solution. Meanwhile, rhodamine 6G, tetraiodofluorescein and phloxin have the same phenomenon of blue shift. Based on these facts, we speculate that the mechanism is probably singlemolecular luminescence because of the limit effect in three dimension space of the polymer. The molecule fluorescence peak was also depending on its environment because the surrounding electron field affected the molecule luminescence in polymer.
