为提高不稳定化合物1-氨基-1-肼基-2，2-二硝基乙烯（AHDNE）的稳定性，进行了AHDNE的包合研究。通过紫外吸收光谱研究，发现对叔丁基（对硝基）杯[n]芳烃（n＝4，6，8）及β-（硝化）环糊精（β-CD和β-NCD）与AHDNE在溶液中存在包合作用。确定了包合物的化学计量比和稳定配合常数。结果表明，包合比为1瞷1，硝化后的主体分子与AHDNE的稳定配合常数比未硝化主体分子高数十倍。对硝基杯[6]芳烃和β-NCD与AHDNE的配合常数达2×104以上。主客体化合物、包合物和物理混合物的X-射线衍射分析证实包合物的形成。β-NCD/AHDNE包合物的感度低于AHDNE和β-NCD的感度。

In order to improve the stability of unstable compound 1-amino-1-hydrazine-2,2-dinitroethylene(AHDNE), the inclu-sion of AHDNE was studied.The presence of inclusion interactions of host compounds p-tertbutyl( p-nitro) calix[ n] arenes( n =4, 6, 8),β-cyclodextrin (β-CD) and β-cyclodextrin nitrate (β-NCD) with AHDNE was demostrated by UV-vis absorption spec-tra.The stoichiometric ratio and stability constants of the inclusion complexes were determined.The results show that the inclu-sion ratio is 1:1 and the stability constants of the inclusion compounds derived from the p-nitrocalix[ n] arenes andβ-NCD are ten times higher than those of their unnitrated precursors.The stability constants of the inclusion complexes coming from both p-nitrocalix[6]arene andβ-NCD reach above 2 ×104.XRD analyses of host -guest compound,inclusion complex and physical mixture confirmed the formation of inclusion complexes.The sensitivities of β-NCD/AHDNE inclusion complex are lower than those of AHDNE andβ-NCD.
