带支链聚乙炔液晶高分子的合成与光学特性
Synthesis and optical properties of a monosubstituted polyacetylene with a short spacer and a biphenyl mesogen
摘要
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 temperaturephotoluminescence is investigated. At room temperature, its solution gives off intense deep-bluephotoluminescence with its dominant emission band located at 380 nm. The 380 nm emission bandscan be assigned to the emission from the isolated chain of the polymer. In order to confirm the originof its photoluminescence, the electronic structures of the liquid crystalline polymer are calculated,and the absorption and photoluminescence axe recorded from a small molecular liquid crystal thatbears a biphenyl core.关键词
