Use of sulfur and selenium compounds as precursors to nanostructured materials

The presently disclosed subject matter provides processes for preparing nanocrystals, including processes for preparing core-shell nanocrystals. The presently disclosed subject matter also provides sulfur and selenium compounds as precursors to nanostructured materials. The presently disclosed subject matter also provides nanocrystals having a particular particle size distribution.

METHODS OF PRODUCING METAL SUFLIDES, METAL SELENIDES, AND METAL SULFIDES/SELENIDES HAVING CONTROLLED ARCHITECTURES USING KINETIC CONTROL

The present invention is directed to methods of preparing metal sulfide, metal selenide, or metal sulfide/selenide nanoparticles and the products derived therefrom. In various embodiments, the nanoparticles are derived from the reaction between precursor metal salts and certain sulfur- and/or selenium-containing precursors each independently having a structure of Formula (I), (II), or (III), or an isomer, salt, or tautomer thereof, where Q1,Q2,Q3,R1,R2,R3,R5, and X are defined within the specification.

A Tunable library of substituted thiourea precursors to metal sulfide nanocrystals

Controlling the size of colloidal nanocrystals is essential to optimizing their performance in optoelectronic devices, catalysis, and imaging applications. Traditional synthetic methods control size by terminating the growth, an approach that limits the reaction yield and causes batch-to-batch variability. Herein we report a library of thioureas whose substitution pattern tunes their conversion reactivity over more than five orders of magnitude and demonstrate that faster thiourea conversion kinetics increases the extent of crystal nucleation. Tunable kinetics thereby allows the nanocrystal concentration to be adjusted and a desired crystal size to be prepared at full conversion. Controlled precursor reactivity and quantitative conversion improve the batch-tobatch consistency of the final nanocrystal size at industrially relevant reaction scales.

Prweparation and thermal stability of optically active 1, 2, 4-triazolium-based ionic liquids

The synthesis of optically active ionic liquids, in a four-step reaction sequence, is described. In the first step an oxirane ring of cyclohexene oxide was opened with 1, 2, 4-triazole, yielding a racemic mixture of (1R,2R)- and (1S,2S)-2-(1H-1, 2, 4-triazol-1-yl)cyclohexanol. Kinetic resolution of the racemate by a lipase catalyzed transesterification with vinyl acetate followed by alkylation (quaternization) of the triazole ring resulted in the appropriate optically active salts formation. After the anion metathesis, thermally stable novel chiral ionic liquids were obtained. ARKAT-USA, Inc.
