摘要：

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.
