WebPBI based H-aggregates suﬀer from one serious limitation: an extremely fast self-trapping of the long-lived exciton into the excimer state.9,10 Excitons in H-aggregates are typically delo-calized over several PBI units, and have an underlying molec-ular arrangement that is quite similar to that in the ground state. WebWe propose a three-state model through localized diabatization to quantitative analyze excited state structures for various herringbone (HB) H-aggregates and demonstrate that for some investigated systems, the low-lying intermolecular charge-transfer (CT) state couples with the bright Frenkel exciton (FE) and forms a dipole-allowed S1 …
