| 摘 要： | 以聚乙烯醇(PVA)为粘胶剂,将四苯基乙烯(TPE)及其衍生物聚集体固载在滤纸上,以有效发挥AIE的特性.为了考察PVA浓度对四苯基乙烯及其衍生物聚集态下发光性能的影响规律,本文研究了PVA浓度分别与TPE、1,1,2,2-四-(4-(5-溴戊氧基)苯基)乙烯(TPE-OR)、(4-二苯基)苯基二苯并富烯(BpPDBF)三种化合物荧光强度之间的关系.实验结果表明,即使水含量不同,三种化合物均对PVA浓度依赖性存在着荧光强度极大值.说明提高PVA浓度,增加溶液粘度,将会使TPE及其衍生物分子内旋转进一步受限,但同时也会妨碍TPE及其衍生物形成更大的聚集体,即荧光强度的变化是这两种作用的综合体现.另外,固载于滤纸上的TPE、TPE-OR、BpPDBF薄膜可以用于检测特定有机溶剂及硝基化合物的挥发气氛,并具有比较灵敏的响应.

| Abstract: | To effectively apply the AIE characteristics, tetraphenylethylenes' aggregates were immobilized by polyvinyl alcohol (PVA) as the adhesive on the filter. The relationship between the concentration of PVA solution and the AIE properties of tetraphenylethylene (TPE), 1,1,2,2-tetra(4-[5-(bromopentyl)oxy]phenyl)ethylene (TPE-OR) and (4-biphenylyl)phenyldibenzofulvene (BpPDBF) was firstly studied in THF-water mixture, respectively. The results showed that the fluorescence intensity of three samples similarly varied with PVA concentration in the presence of different water fraction in THF-water mixture. It indicated that the restricted intramolecular rotations of the compounds are impelled with the increase of PVA concentration. Unfortunately, it would go against the appearance of greater aggregate when PVA concentration is further increased. As a result, the alteration of fluorescence intensity depended on both of them. In addition, TPE, TPE-OR and BpPDBF films which are fixed on filter paper using PVA as adhesion agent can be used to test volatile atmosphere of specificorganic solvents and nitro-compounds, and responses are sensitive. |
