The invention provides compounds that may inhibit influenza virus replication, and are accordingly useful for treatment of viral infections caused by influenza virus. The invention further provides pharmaceutical compositions containing these compounds and methods of using these compounds to treat or prevent viral infections caused by influenza virus.

A thermally activated delayed fluorescent material, a method of fabricating the same, and an electroluminescent device are provided. An electron donor and an electron acceptor of the thermally activated delayed fluorescent material are connected with each other by a hexatomic ring. Thus, luminous efficiency of the thermally activated delayed fluorescent material can be improved.

The present disclosure relates to compounds of Formulae (I) or (II):
