On April 11, 2002, Woo, Tae-Woo; You, Hong; Han, Taek-Kyu; Joo, Dong-Jin; Kwon, Soon-Ki; Kim, Yun-Hi; Shin, Dong-Cheol; Jung, Sang-Yun published a patent.SDS of cas: 146370-51-6 The title of the patent was Poly(phenylenevinylene) derivatives substituted with spirobifluorenyl group(s) and electroluminescent devices prepared using the same. And the patent contained the following:
Organic electroluminescent polymers are described by the general formula I (≥1 of A and B = II; when one of A and B is not II, it is R5; R3, R4, and R5 = independently selected hydrogen, phenoxy group substituted with C1-20 alkyl groups, C1-20 alkoxy groups, C1-20 alkoxyphenyl groups, C1-20 alkyl groups, and C3-21 ω-methoxy polyethylene oxide groups’ m = 0-50,000; n = 1-100,000; and n > m). Electroluminescent devices are described in which the organic electroluminescent polymers are used as a light-emitting layer, hole-transport layer or electron-transport layer. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).SDS of cas: 146370-51-6
