Tuning the singlet–triplet energy gap of AIE luminogens: crystallization-induced room temperature phosphorescence and delay fluorescence, tunable temperature response, highly efficient non-doped organic light-emitting diodes

Tuning singlet–triplet energy gap of AIE luminogens: crystallization-induced phosphorescence, delay fluorescence and efficient non-doped OLEDs.

Charge-transfer-featured materials—promising hosts for fabrication of efficient OLEDs through triplet harvesting via triplet fusion

An ICT-featured compound with a small ΔEST but a lower lying 3ππ* state than 3CT state is demonstrated to show P-type rather than E-type delay fluorescence, and is a quite promising OLED host.
