A Readily Obtained Alternative of 1H-benzo[f]indole towards Room Temperature Ultralong Organic Phosphorescence [PDF]

, 2022
1H-benzo[f]indole (Bd) is a significant unit in the field of room temperature ultralong organic phosphorescence (RTUOP). However, the synthesis of Bd is rather hard and of low yield, which greatly limits the wide applications of RTUOP.
