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. Fluorescence properties of a monosubstituted derivative of polyacetylene were studied at room temperature, and films of monosubstituted derivatives of such polyacetylene emit strong green fluorescence. The main fluorescence peak at 510 nm and the two minor peaks at 440 nm and 380 nm, respectively. The two fluorescence peaks at 510 nm and 440 nm are the excitation peaks of the polymer material The main and minor luminescence peak of the compound, while the fluorescence peak at 380 nm is the luminescence peak of a single polymer chain.These spectral changes can be explained by the structural changes that occur in the polymer.
