共轭高聚物双分子链中激子生成的动力学研究

通过对耦合共轭高分子双链中激子生成的动力学研究，讨论了受到光激发后，激子在分子内或分子间生成的制约因素.激子的生成除了受分子链间耦合强度的制约，还受到光激发模式的影响.结果表明，激子既可以在分子内生成，也可以在耦合分子间生成.增大分子之间的相互作用强度，可以增大在分子之间生成激子的概率.

Dynamics study of exciton formation in dual conjugated polymer molecular chains

By the dynamics study of exciton formation in two coupling molecular chains of conjugated polymer, the dominant formation mechanism of intra-molecule or inter-molecuole exciton is discussed after photo-excitation. Exction formation is controlled by the interaction strength of the molecules. Besides, It is also influenced by the pattern of the photoexctation. The results show that an exciton can form within a molecule, and it can also be created between two coupling molecules after photoexcitaton. Increasing the coupling strength of the molecules, the occasion of the exciton formed between the molecules is increased.
