On October 31, 2017, Moon, Seong Yun; Kim, Seul Gi; Lee, Seon Hui; Choi, Yeon Hui; Park, Chi Hyeon published a patent.Application of 58142-46-4 The title of the patent was Preparation of condensed polycyclic compounds for organic electric device. And the patent contained the following:
Disclosed are compounds I [X = N-L1-R1, S, O, etc.; n, m = 0 or 1 such as m+n≥1 (when n or m is 0, then A or B, at each occurrence, represents a single bond); A, B = independently single bond, N-L2-R2, S, etc.; Z1-Z12 = independently CR3 or N with a proviso that at least one of Z1-Z12 is N; R1-R3 = independently H, aryl, fluorenyl, etc.; L1, L2 = single bond, arylene, fluorenylene, etc.] and electronic device thereby. For example, red electroluminescent device comprising II (phosphorescent host material) showed improvements in luminous efficiency, lifespan and driving voltage compared to device using CBP. The experimental process involved the reaction of 4-Bromo-5-nitroisoquinoline(cas: 58142-46-4).Application of 58142-46-4
