On August 25, 2014, Oh, Cheon Rim; Lee, Won Jung; Kim, Yeong Seong; Lee, Min Seon; Lee, Seung Min; Jeon, Eun Ju; Choi, Don Su; Moon, Bong Seok; So, In Yeong; Lee, Jae Yeol; Ju, Seong Hu published a patent.HPLC of Formula: 93012-36-3 The title of the patent was Preparation of phenanthrene compounds as organic electroluminescence device materials. And the patent contained the following:
Disclosed are compounds I [Ar1-Ar3 are independently (un)substituted alkyl, aryl, heterocyclyl, arylamino, etc.; R1-R6 are independently H, CN, (un)substituted alkyl, alkoxy, etc.; n is 0-3; with the proviso that R1-R6 are not hydrogen at the same time; when Ar2 and Ar3 are aryl, at least one of Ar2 and Ar3 is (un)substituted anthracene, pyrene, diphenylfluorene, etc.]. Example compound II was prepared by the sequential palladium-catalyzed coupling reaction of compound III with pyren-2-ylboronic acid and diphenylamine in 25% yield for two steps. Blue electroluminescent device comprising an invention compound (light-emitting layer material) showed improvements in efficiency and life span compared to device using previously reported compound (CBP). The experimental process involved the reaction of 5,5′-Dimethyl-[1,1′-biphenyl]-2,2′-dicarboxylic acid(cas: 93012-36-3).HPLC of Formula: 93012-36-3
