    摘要: A method of purifying ammonia borane is provided whereby crude ammonia borane is dissolved in a basic aqueous solution, the solution is heated to decompose and precipitate impurities found in the crude ammonia borane, and the impurities are separated by filtration. The aqueous solution containing dissolved ammonia borane is then cooled to a temperature of from 10° C. to −10° C., to precipitate the ammonia borane, which is recovered and dried to yield a high-purity product.

    摘要: Described are nonlinear optical (NLO) crystals, including aluminum-borate NLO crystals, that have low concentrations of contaminants that adversely affect the NLO crystal's optical properties, such as compounds that contain transition-metal elements and/or lanthanides, other than yttrium, lanthanum, and lutetium. Some NLO crystals with low concentrations of these contaminants are capable of second harmonic generation at very short wavelengths. Also described are embodiments of a method for making these NLO crystals. Some embodiments involve growing a single NLO crystal, such as an aluminum-borate NLO crystal, from a mixture containing a solvent that is substantially free of harmful contaminants. The described NLO crystals can be used, for example, in laser devices.

    摘要: The invention provides new methods for synthesis of large boron hydride clusters, e.g., boron hydride molecules of the formula BnHm where 5≦n≦96 and m≦n+8, wherein m and n satisfy the electron counting rules of macropolyhedral boranes. The invention is particularly useful for synthesis of octadecaborane (B18H22). Preferred methods of the invention include iteratively generating a conjugate acid from a salt of the [BaHb]c− or [Bn+2Hm−4]2− anion followed by degradation under conditions conducive to concentrating and drying of the conjugate acid to provide a borane BnHm and residual salt of the [BaHb]c− or [Bn+2Hm−4]2− anion which is reused in the method of synthesis. The invention further provides isotopically enriched boranes, particularly isotopically enriched 10B18H22 and 11B18H22.
