Conjugation-Length Dependent Interplay Between Charge Transfer and Locally Excited States in Sequence-Defined Donor-Acceptor Substituted Oligo(Phenylene Ethynylene)s.
Oligo(para-phenylene ethynylene)s (OPEs) serve as well-defined model compounds to understand electronic effects in conjugated macromolecules. Here, we report a sequence-defined series of OPEs capped with a di-tert-butylcarbazole (DtBCz) donor and a triphenyltriazine (Trz) acceptor to investigate how the donor-acceptor...
