摘要：

A charge-transfer-featured naphthalimide derivative with a small exchange energy but a lower lying (3)pi pi* state than (CT)-C-3 state is found to contribute to triplet harvesting through a P-type rather than an E-type delayed fluorescence, and could act as a quite promising host to achieve highly efficient OLEDs.
