And the patent contained the following:
A compound for organic optoelectronic device and a display device comprising the same having high-efficiency is provided. The compound is represented by formula 1, wherein T is a substituted or unsubstituted C2 to C30 heterocyclic group containing at least two nitrogen, L is a single bond, a substituted or unsubstituted C6 to C30 arylene group, a substituted or unsubstituted C2-C30 heteroarylene group, or its combination, X is oxygen or sulfur, Ar is a substituted or unsubstituted C6-C12 aryl group, R1-R4 each independently represent hydrogen, deuterium, a substituted or unsubstituted C1-C20 alkyl group, a substituted or unsubstituted C2-C20 alkenylene group, a substituted or unsubstituted C6-C20 aryl group, a substituted or unsubstituted C2-C30 heterocyclic group, or its combination, at least two of R1-R4 are connected to adjacent groups to form at least one substituted or unsubstituted aromatic ring or substituted or unsubstituted heteroaromatic ring, Ra is hydrogen, deuterium, a substituted or unsubstituted C1-C4 alkyl group, or a substituted or unsubstituted C6-C12 aryl group, Means that at least one hydrogen is substituted with deuterium, a C1-C10 alkyl group, a C6-C12 aryl group, or a C2-C10 heteroaryl group. Further, the compounds for an organic optoelectronic device is selected from the compounds represented in Group 1. 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
