Patent number: 11581489Abstract: A white light emitting material having a chemical structural formula represented by formula (I), a preparation method thereof and application thereof. The preparation method comprises subjecting tris(4-iodophenyl)amine and 4-methoxyphenylacetylene or tris(4-iodophenyl)amine and methyl 4-ethynylbenzoate to a coupling reaction under protection of a protective gas and catalysis of a Pd/Cu mixed catalyst, to obtain the white light emitting material. A novel temperature-sensitive light emitting material is synthesized through a one-step method. The material is applied to the field of diode luminescence based on the temperature-sensitive characteristic. White light luminescence can be finally realized only by reasonably controlling the temperature and duration time during heating a substrate. Compared with the existing art, the method greatly saves raw material costs and manufacturing process costs, and provides a novel idea and strategy for use of a white organic light emitting diode.Type: GrantFiled: July 31, 2020Date of Patent: February 14, 2023Assignee: South University of Science and Technology of ChinaInventors: Xiaomeng Li, Jieshun Cui, Xianglin Wang, Zhaoyu Zhang

Publication number: 20210154156Abstract: Disclosed is application of emodin in inhibiting amyloid ?-protein (A?) accumulation, improving cognitive and memory abilities, and reducing senile plaques. Alzheimer's disease (AD) is a neurodegenerative disease which is characterized in that nerve cell fibers are entangled. A? plaques are deposited, and a cognitive function is impaired to a pathological feature, and extracellular toxicity accumulation of A? is considered as one of main links of AD pathogenesis. In the present invention, it is discovered that emodin can obviously inhibit accumulation of an A?42 monomer and formation of fibers and inhibit formation of a ? secondary structure, can improve spatial memory learning ability of an AD mouse, and can obviously clear amyloid plaques in APP/PS1 double-transpenic AD model mouse brain tissues. It shows that emodin can be applied to treatment of AD, and research and development of related medicaments.Type: ApplicationFiled: January 14, 2019Publication date: May 27, 2021Applicant: NorthEast Normal UniversityInventors: Xiaomeng LI, Lichun WANG, Xiaowan WANG, Jiale LI, Chuanjian LAN, Jiang LI
