Abstract: Abstract Four novel fluorescent molecules based on pentavalent phosphoryl center π-conjugated heterocycles (PCCH) as acceptor have been constructed by ether, sulfide, and sulfonyl groups as tethering groups and phenoxazine or phenothiazine as the donor. Their… read more here.

Abstract: Phthalimide-based "D-N-A" emitters o-AI-Cz, m-AI-Cz and p-AI-Cz showed TADF and RTP properties due to their small ΔEST in both film and crystalline states. In particular, o-AI-Cz exhibited an ultralong RTP with a lifetime of 602… read more here.
