Abstract
The exciplex-forming system occurred at the donor -acceptor interface that can emit deep blue emission is still very rare due to the scarcity of appropriate donor and acceptor molecules. The design, synthesis and characterizations of two phenyldibenzophosphole oxide-based acceptors with para- and meta-substituted benzonitrile peripherals for fine-tuning the frontier orbitals are reported. With suitably selected indenocarbazole-based donors, blue to deep blue exciplex-forming systems with thermally activated delayed fluorescence were identified and verified by time-resolved photoluminescence.
