This method uses lactone monomer as reaction raw material, thiol-alcohol as initiator, and diphenyl phosphate as organic catalyst to catalyze and synthesize the thiol-functionalized polyester polyols. The present invention provides a method which is simple, inexpensive, easily controllable and environmentally friendly to prepare thiol-functionalized polyester polyols with the easily available and controllable catalyst. The method can selectively catalyze the ring opening polymerization of lactone to prepare thiol-functionalized polyester polyols using the organic catalyst.

专利号:US-10604540-B2 优先权日:2016-09-16 标题 :Controlled synthesis of polymeric perylene diimide and applications thereof 发明人:MAZAHERIPOUR AMIR; BURKE ANTHONY; GORODETSKY ALON 权利人:UNIV CALIFORNIA 摘要:Perylene diimide phosphoramidite derivatives and methods for polymerization of perylene diimide phosphoramidite derivatives and applications thereof are provided. Compounds comprise at least an electronically active base surrogate and may also include a solubilizing functionality. The base surrogate may be comprised of an electrochemically active perylene diimide (PDI) molecule, the solubility chain may comprise a PEG functionality, and the PDI may further comprise a phosphoramidite functionality as an imide substituent. The phosphoramidite functionality may be used as a chemical coupling handle for use with established nucleic acid synthesis protocols and/or automated synthesis. One or more aromatic core functionalizations may be incorporated into the PDI molecules to allow for tuning the molecule's electronic and optical properties. One or more functional terminal groups may be incorporated into the PDI molecules, such as, for example terminal thiols for attachment to gold substrates and terminal ferrocenes for electrochemical measurements, among others.

The additional H 2 can be used to partially hydrogenate biomass oil prior to co-processing the biomass oil in the fluid catalytic cracking system. Additionally or alternately, the additional synthesis gas can represent an additional yield of products from the process, such as an additional yield that can be used for synthesis of further liquid products.
专利号:US-2024352312-A1 优先权日:2021-06-25 标题:Microemulsion template assisted synthesis of cadmium-free near-infrared quantum dots based on i-iii-vi ternary semiconductors 发明人:WANG JUN 权利人:QUANTUM TECH GROUP 摘要:A method for making ternary core-shell semiconductor nanoparticles includes providing an emulsion including droplets dispersed in a continuous phase of a non-polar solvent. The droplets include a solution of ions of a Group I element and ions of a Group III element in a polar solvent, and are encapsulated by an interfacially active material. The emulsion is exposed to ions of a Group VI element to cause a reaction, thereby forming nanoparticles in the droplets. The nanoparticles in the droplets are with a first precursor to grow a shell on the nanoparticles, thereby forming core-shell nanoparticles. The core-shell nanoparticles are extracted from the emulsion; thermally annealed; and reacted with a second precursor to further grow the shell on the nanoparticles, thereby forming ternary core-shell semiconductor nanoparticles.
