J‑Type Heteroexciton Coupling Effect on an Asymmetric Donor–Acceptor–Donor-Type Fluorophore
The
novel donor–acceptor–donor (D–A–D)-type
fluorophore with an asymmetric structure is reported. The twisted-induced
charge transfer (TICT) luminescence was observed. The degree of charge
transfer and radiative rate constant in the luminescence increased
simultaneously with increase in orientational polarizability of solvents.
In contrast to the numerous CT fluorophore researches, this behavior
has never been previously observed. This characteristic behavior reveals
the existence of an effective exciton coupling between the CT states
in the donor–acceptor–donor-type fluorophore for the
first time
