Abstract:
Efficient excited-state transport is essential for the optimal performance of photoelectronic devices, which, however, is very limited in organic semiconductors (OSCs) due to the presence of poorly diffusive triplet-states. Herein, we report a bridging group enabled triplet-state manipulation strategy for suppressing the intersystem crossing (ISC) and thereby realizing a promoted and directional singlet-state exciton transport in anthracene derivative-based OSCs. Furthermore, this approach is demonstrated to be applicable to various anthracene derivatives, such as bridged anthracene-benzothiophene and anthracene-benzene systems, suggesting its broad generalizability for optimizing the exciton/energy transport properties of OSCs.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
