[Bis(imidazolyl)-BH ] [bis(triazolyl)-BH ] and [bis(imidazolyl)-BH ] [tris(triazolyl)-BH] were synthesized, the cations and anions of which were functionalized with B-H groups and azoles. As B-H groups contribute to the hypergolic activity and azole groups improve the energy output, the resulting ionic liquids exhibited ignition delay times as low as 20 ms and energy outputs as high as 461.1 kJ mol . In addition, densities (1.07-1.22 g cm ) and density-specific impulse (≈360 s g cm ) values reached a relatively high level. These ionic liquids show great promise as sustainable rocket fuels.
合成了[双（咪唑基）-BH₄] [双（三唑基）-BH₄]和[双（咪唑基）-BH₄] [三（三唑基）-BH₄]，其阳离子和阴离子用B-H基团和唑类进行了功能化。由于B-H基团有助于自燃活性，唑类基团提高能量输出，所得离子液体的点火延迟时间低至20毫秒，能量输出高达461.1千焦/摩尔。此外，密度（1.07 - 1.22克/立方厘米）和密度比冲（≈360秒·克/立方厘米）值达到了相对较高的水平。这些离子液体作为可持续火箭燃料显示出巨大的潜力。
