| 摘 要： | 在室温下,对聚乙炔的一种单取代衍生物的荧光特性进行了研究.这种聚乙炔的单取代衍生物的薄膜能够发出强的绿色荧光,其荧光光谱的主要荧光峰位于510 nm,而它的两个次要荧光峰分别位于440 nm和380 nm.位于510 nm、440 nm的两个荧光峰分别是该高分子材料所形成的激发缔合物的主要和次要发光峰,而位于380 nm的荧光峰是单条高分子链的发光峰.这些光谱方面的变化可用该高分子发生的结构上的变化来解释.

| Abstract: | A side-chain liquid crystalline polymer,poly{n-(4'-hexylcarbonyl-biphenyl-4-oxy)]-1- propyne},is synthesized.It is a member of mono-substituted polyacetylenes.Its room temperature photoluminescence is investigated.At room temperature,its solution gives off intense deep-blue photoluminescence with its dominant emission band located at 380 nm.The 380 nm emission bands can be assigned to the emission from the isolated chain of the polymer.In order to confirm the origin of its photoluminescence,the electronic ... |
