On May 8, 2008, Kubo, Masataka; Ito, Takahito; Shoyama, Masashi published a patent.Application of 146370-51-6 The title of the patent was Organic-inorganic hybrid phosphors, their preparation, and their use for white light-emitting materials and capsule-type endoscopes. And the patent contained the following:
The organic-inorganic hybrid phosphors, useful for white light-emitting materials and capsule-type endoscopes, contain 蟺-conjugated poly(arylenevinylenes) in granular silica and are prepared by sol-gel processing of 蟺-conjugated poly(arylenevinylenes) having phosphonium end groups and alkoxysilanes. Thus, reaction of 4-methoxyphenol and 1-bromo-2-ethylhexane gave 4-(2-ethylhexyloxy)anisole, which was converted into a dialdehyde derivative (A) and diphosphonium chloride derivative (B) via a bis(chloromethyl) derivative A and B were copolymerized in CHCl3 in the presence of NaOEt to give a 蟺-conjugated poly(arylenevinylene), which was stirred with Si(OEt)4 in aqueous EtOH solution containing 2-amino-2-hydroxymethyl-1,3-propanediol dodecylsulfate salt and NH4OH to give an organic-inorganic hybrid phosphor. A UV-emitting diode chip was potted with a mixture of the phosphor, other phosphors prepared in similar manners, and silicone resins (KER-2667A and KER-2667B) to give a white light-emitting diode showing a UV peak at 373 nm and a broad spectrum with wavelength range 400-700 nm. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Application of 146370-51-6
