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.endeep blue emission | exciplex | phosphole | rigid acceptor | synthesis | Thermally-activated delayed fluorescence[SDGs]SDG7journal article10.24820/ark.5550190.p012.0132-s2.0-85177885077https://api.elsevier.com/content/abstract/scopus_id/85177885077
