摘要:It relates to the field of synthetic macromolecular chemistry, and discloses a method for one-step synthesis of thiol-functionalized polyester polyols by organic catalysis. 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.

摘要:Hydroxy sulfonic acids in general and isethionic acid (2-hydroxy ethyl sulfonic acid) in particular can be prepared at 99+% purity and good yields by the selective oxidation of a precursor hydroxy mercaptan with hydrogen peroxide. The resulting product is pure enough to be used directly in the synthesis of sulfo-acrylic esters which are finding considerable use as stabilizers in producing vinylidene chloride copolymers used for FDA approved packaging films.

标题:Microemulsion template assisted synthesis of cadmium-free near-infrared quantum dots based on i-iii-vi ternary semiconductors

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.

摘要:Described is a direct method for the fabrication of resorcinarene nanocapsules by photopolymerization of compounds of formula (I), such as resorcinarene tetraalkene tetrathiol (RTATT), in the absence of any template or preorganization. Further, by varying the polymerization media, a variety of other polymeric architectures like lattices, fibrous networks, and nanoparticles were obtained. The morphology and structure were characterized by transmission electron microscopy, energy dispersive spectroscopy, scanning electron microscopy, dynamic light scattering, infrared and nuclear magnetic resonance spectroscopy. These morphologically distinct resorcinarene polymeric architectures contain residual thiol and ene functional groups offering potential functionalization opportunities.
