Abstract: 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.
