本文综述了电致发光介晶夹套液晶聚合物的结构设计和发光性能评价的最新进展。通过应用MJLCP的概念，两个主要的发色团结构单元，具有大空间位阻的电子传输和空穴传输单元，单独或一起连接到主链上。我们强调的结构-性能-性能的电致发光MJLCP的关系。通过抑制共轭结构的聚集、荧光猝灭和激基缔合物的形成，可以提高器件的性能。
This critical review covers the recent progress in the chemical structure design and light-emitting performance evaluation of electroluminescent mesogen-jacketed liquid crystalline polymers (MJLCPs). By applying the concept of MJLCPs, two main chromophoric building units, electron-transporting and hole-transporting units with large steric hindrance, are attached to the backbones solely or together. We highlight the structure–properties–performance relationships of electroluminescent MJLCPs. Device performances can be enhanced by the “jacketing effect”, which inhibits the aggregation of conjugated structures, fluorescence quenching, and excimer formation.
