Abstract:Red luminescent materials are essential components for full color display and white lightening based on organic light‐emitting diode (OLED) technology, but the extension of emission color towards red or deep red region generally leads to decreased photoluminescence and electroluminescence efficiencies. Herein, we wish to report two new luminescent molecules (2CNDPBPPr‐TPA and 4CNDPBPPr‐TPA) consisting of cyano‐substituted 11,12‐diphenyldipyrido[3,2‐a:2',3'‐c]phenazine acceptors and triphenylamine donors.
