On February 17, 1999, Jin, Sung-Ho; Kim, Woo-Hong; Son, Byung-Hee; Song, In-Sung; Han, Eun-Mi published a patent.Electric Literature of 146370-51-6 The title of the patent was Organic electroluminescent polymer for light-emitting diode and devices therefrom. And the patent contained the following:
A light-emitting polymer for an electroluminescent display comprises a polymer having a dialkylphenylene moiety and a carbazole moiety I, where R1-R3 are independently C2-13 aliphatic alkyl or C5-16 branched alkyl; p = 5-100; and/or a polymer having an oxadiazole moiety and a poly(p-phenylenevinylene) moiety, and optionally a conventional polymer and a lower-mol. fluorescent dye. The polymer is applied to a light-emitting layer of a light-emitting diode having a cathode/light-emitting layer/anode structure, a cathode/buffer layer/light-emitting layer/anode structure, or a cathode/hole-transporting layer/light-emitting layer/electron-transporting layer/anode structure. Thus, a 2,5-bis(p-bromophenyl)-1,3,4-oxadiazole-1-methoxy-4-(2-ethylhexyloxy)-2,5-phenylboronic acid copolymer (monomer preparations given) was prepared, which was soluble in an organic solvent and showed excellent electron transport properties. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Electric Literature of 146370-51-6
