标 题:Precursor chemistry for quantum dot synthesis enabling temperature-independent modulation of reactivity
发明人：HAN HEE-SUN; PARK JOONHYUCK
权利人:UNIV ILLINOIS
摘要:Provided herein are methods of making a high-quality quantum dot (QD), including by providing anion precursor chemistry that enables chemical modulation of precursor reactivity, thereby, allowing independent optimization of reaction temperature and precursor reactivity to systematically grow high quality QDs and by providing specially configured tunable precursors and related chemistry to facilitate separate reaction pathways for nucleation and growth, thereby accessing heat-up based synthesis of high-quality QD, including core-shell QDs. The methods may include providing a base-QD and a first anion or cation precursor having a composition comprising an anion or a cation element, respectively, and a modification agent. At least one add-layer is grown on the base-QD at a growth temperature, thereby making the high-quality QD comprising the base-QD and the at least one add-layer. At least one add-layer may have a composition comprising an add-layer cation element and an add-layer anion element.

标 题 :Polysulfide polyols, their production and use in the synthesis of polyurethanes
发明人：BALBO BLOCK MARCO; RHUDY KEVIN; FLECKENSTEIN CHRISTOPH
权利人:BASF SE
摘要:The present invention relates to sulfur containing polyols, a process for their production by reaction of at least one unsaturated alcohol A with elemental sulfur, wherein the unsaturated alcohol A has only one carbon-carbon double bond-unsaturation per molecule. The sulfur containing polyols are used in the production of polyurethanes, in particular rigid foam polyurethanes, for high-temperature pipe insulation applications.

摘要:In one aspect, the present invention provides a hyperpolarizable organic chromophore. The chromophore is a nonlinear optically active compound that includes a Ï€-donor conjugated to a Ï€-acceptor through a Ï€-electron conjugated bridge. In other aspects of the invention, donor structures and acceptor structures are provided. In another aspect of the invention, a chromophore-containing polymer is provided. In one embodiment, the chromophore is physically incorporated into the polymer to provide a composite. In another embodiment, the chromophore is covalently bonded to the polymer, either as a side chain polymer or through crosslinking into the polymer. In other aspects, the present invention also provides a method for making the chromophore, a method for making the chromophore-containing polymer, and methods for using the chromophore and chromophore-containing polymer.
