Chromophore aggregates are capable of a wide variety of excited-state dynamics that are potentially of great use in optoelectronic devices based on organic molecules. For example, singlet fission, the process by which a singlet exciton is down converted into two triplet excitons, holds promise for extending the efficiency of solar cells, while other processes, such as excimer formation, are commonly regarded as parasitic pathways or traps. Other processes, such as symmetry-breaking charge transfer, where the excited dimer charge separates into a radical ion pair, can be both a trap and potentially useful in devices, depending on the context. Thus, an understanding of the precise mechanisms of each of these processes is vital to designing tailor-made organic chromophores for molecular optoelectronics.

分子二聚体中的混合电子态：连接单重态裂变，准分子形成和对称断裂电荷转移。
发色团聚集体能够具有多种激发态动力学，这在基于有机分子的光电器件中可能很有用。例如，单重态裂变（单重态激子被下转换为两个三重态激子的过程）有望扩展太阳能电池的效率，而其他过程（例如准分子的形成）通常被认为是寄生途径或陷阱。取决于上下文，其他过程（例如，对称性破坏的电荷转移，其中被激发的二聚体电荷分离成自由基离子对）可能既是陷阱，也可能在设备中有用。因此，对每个过程的精确机理的理解对于设计用于分子光电的量身定制的有机发色团至关重要。
