And the patent contained the following:
Disclosed are compounds I [X = O, S or Se; L1, L2 = independently single bond, (un)substituted arylene or (un)substituted heteroarylene (containing heteroatom selected from O, N, S, etc.); Ar1, Ar2 = independently (un)substituted aryl or (un)substituted heteroaryl (containing heteroatom selected from O, N, S, etc.); Q1’s are same or different; one of R1-R4 is a single bond to nitrogen atom; Z, R1-R5 = independently H, deutero, (un)substituted alkyl, etc.; m = 1-8; when Z is plural, they are same or different; p, q = 1-3; when Ar1 is plural, they are same or different; when Ar2 is plural, they are same or different]. Electroluminescent device comprising an invention compound, e.g., II, showed improvements in brightness, light-emitting efficiency and lifespan compared to device using previously reported compound The experimental process involved the reaction of 7-Bromo-2-phenylbenzo[d]oxazole(cas: 1268137-13-8).Safety of 7-Bromo-2-phenylbenzo[d]oxazole
