摘　　要：Aromatic carbonyls have evoked sustained attention in the field of room-temperature phosphorescence(RTP).The introduction of carbonyl groups is a general way to achieve RTP for their effective intersystem crossing(ISC)by improving spin-orbit coupling(SOC).With further molecular design and processing strategies,aromatic carbonyls materials with multi-functional and high efficiency ultralong organic phosphorescence(UOP)can be obtained.This review summarizes the mechanism of aromatic carbonyls with UOP in pure aromatic carbonyls and their multi-component systems.Some detailed strategies for improving UOP performance are further introduced.The summary and outlook are presented to expound on the advances and lack of aromatic carbonyls.Further development directions and requirements are also put forward.
