On November 3, 2017, Huang, Jinhai; Su, Jianhua published a patent.Computed Properties of 1268137-13-8 The title of the patent was Spirofluorene type organic electroluminescent compound and organic electroluminescence device. And the patent contained the following:
The invention relates to spirofluorene type organic electroluminescent compounds of formula I, wherein X is one of N, O, S and NR14; R1 t R14 are independently H, C1-12alkyl, (un)substituted C3-30 (hetero)aryl, etc., method for their preparation and their use in organic electroluminescence device. The compound has good thermal stability, high light emission efficiency and high luminous purity, and can be used for producing organic electroluminescent device to be applied to the field of organic solar cell, organic thin film transistor or organic photoreceptor. The invention further provides an organic electroluminescence device, which comprises an anode, a cathode and an organic layer. The organic layer at least contains at least one of luminous layer, hole injection layer, hole transmission layer, hole barrier layer, electron injection layer and electron transmission layer. At least one layer of the organic layer contains the compound represented by the structural formula I. The organic electroluminescent device has the advantages of good electroluminescent efficiency, excellent color purity and long service life. The experimental process involved the reaction of 7-Bromo-2-phenylbenzo[d]oxazole(cas: 1268137-13-8).Computed Properties of 1268137-13-8
