  [双（咪唑基）–BH2] + [双（三唑基] –BH2]-高密度和高能容量的离子液体

  摘要：

  合成了[双（咪唑基）-BH 2 ] + [双（三唑基）-BH 2 ] -和[双（咪唑基）-BH 2 ] + [三（三唑基）-BH] -，其阳离子和阴离子为用BH基团和吡咯官能化。由于B H基团有助于高分子量活性，而唑基基团改善了能量输出，因此所得到的离子液体表现出低至20 ms的点火延迟时间和高至461.1 kJ mol -1的能量输出。此外，密度（1.07–1.22 g cm -3）和特定密度的脉冲（≈360s g cm -3））值达到了较高的水平。这些离子液体有望作为可持续的火箭燃料。

  catalysts for the room-temperature reduction of CO2 to methanol in the presence of sodium borohydride. The catalysts feature unusual stability, particularly for a base metal catalyst, enabling >1.1 million turnovers of CO2. Moreover, while other systems involve more expensive reducing reagents, sodium borohydride is inexpensive and easily handled. Furthermore, effecting reduction in the presence of water enables

  The product subject of invention relates to the addition of the inhibitor "Boronium-doped corrosion inhibitor (synthesized product)" obtained from the product boron to the system as corrosion preventer for the required applications and to increase the corrosion resistance of the metal (e.g. St37 metal) by increasing the amount of concentration in the system. The most important distinctions are that the product we synthesized is dissolved in water and contains boron element which is found abundant in our country. An inhibition effect of up to 90% has been determined using 0.0025 Molar product, which we specified as the maximum concentration. In this context, the product precludes the patents set out in other literature.

• Influence of Pyrazolate vs <i>N</i>-Heterocyclic Carbene Ligands on the Slow Magnetic Relaxation of Homoleptic Trischelate Lanthanide(III) and Uranium(III) Complexes

  Two isostructural series of trigonal prismatic complexes, M(Bp(Me))(3) and M(Bc(Me))(3) (M = Y, Tb, Dy, Ho, Er, U; [Be-Me](-) = dihydrobis(methypyrazolyl)borate; [Bc(Me)](-) = dihydrobis(methylimidazolyl)borate) are synthesized and fully characterized to examine the influence of ligand donor strength on slow magnetic relaxation. Investigation of the dynamic magnetic properties reveals that the oblate electron density distributions of the Tb3+, Dy3+, and U3+ metal ions within the axial ligand field lead to slow relaxation upon application of a small dc magnetic field. Significantly, the magnetization relaxation is orders of magnitude slower for the N-heterocyclic carbene complexes, M(Bc(Me))(3), than for the isomeric pyrazolate complexes, M(Bp(Me))(3). Further, investigation of magnetically dilute samples containing 11-14 mol % of Tb3+, Dy3+, or U3+ within the corresponding Y3+ complex matrix reveals thermally activated relaxation is favored for the M(Bc(Me))(3) complexes, even when dipolar interactions are largely absent. Notably, the dilute species U(Bc(Me))(3) exhibits U-eff approximate to 33 cm(-1), representing the highest barrier yet observed for a U3+ molecule demonstrating slow relaxation. Additional analysis through lanthanide XANES, X-band EPR, and H-1 NMR spectroscopies provides evidence that the origin of the slower relaxation derives from the greater magnetic anisotropy enforced within the strongly donating N-heterocyclic carbene coordination sphere. These results show that, like molecular symmetry, ligand-donating ability is a variable that can be controlled to the advantage of the synthetic chemist in the design of single-molecule magnets with enhanced relaxation barriers.
