Due to its great scientific and commercial value, polymer light-emitting diodes (PLEDs) have drawn much attention. In recent years, the continuous development and further research of various new materials have made PLED devices increasingly practical. The structural design of polymer electroluminescent material is the soul of the development of new materials. In this paper, we summarize the basic principles and design points of the structural design of polymer luminescent materials in combination with the work of our group, and introduce in detail the design methods of monomolecular structures and their related Basic ideas and theories, the influence of aggregate state structure on the performance of materials and devices is analyzed, and some basic methods of the design of aggregate state structure are summarized. Finally, the general idea of the structural design of polymer luminescent materials is proposed, and the research and development directions are also prospected.
