Novel luminescent liquid crystals were synthesized by introducing a mesogenic cyanobiphenylyl side chain to a luminescent naphthalene core. The 1,5-naphthalene derivatives were thermotropic liquid crystals showing monotropic phase transition, while 2,6-naphthalene derivatives showed an enantiotropic behavior. All compounds had an intense bluish emission in the solid, liquid crystal, and isotropic liquid states, which was investigated by UV–vis and PL spectroscopies.
通过将一种介质性氰基联苯侧链引入发光萘核心,合成了新型发光液晶。1,5-萘衍生物是具有单调相变的热致液晶,而2,6-萘衍生物则表现出外消旋行为。所有化合物在固态、液晶态和各向同性液态下均具有强烈的蓝色发光,这通过紫外-可见光和荧光光谱进行了研究。
