On March 28, 2013, Ono, Yohei; Shiren, Kazushi; Kageyama, Akiko published a patent.Category: chlorides-buliding-blocks The title of the patent was Benzofluorenes bearing diarylamino and 9-carbazolyl groups, materials containing them for emitter layers of organic electroluminescent devices, and displays and lighting systems. And the patent contained the following:
The title benzofluorenes are represented by I [R = C1-6 alkyl, C3-6 cycloalkyl, (C1-4 alkyl-substituted) C6-24 aryl, (C1-4 alkyl-substituted) C5-24 heteroaryl; one of A and B = (substituted) 9-carbazolyl, the other of A and B = diarylamino]. The title organic electroluminescent devies, preferably, blue-emitting, show high color saturation and long service life. Preferable substances for electron-transporting layers and/or electron-injecting layers of the devices are also disclosed. The experimental process involved the reaction of 2-Chloro-4-methyl-1-nitrobenzene(cas: 38939-88-7).Category: chlorides-buliding-blocks
