【Abstract】 Two new clathrate hosts characteristic of a chela - shaped molecular back bone, trans - 1,2 -biphenyl -1,2- acenaphthendiol 1 and cis -1,2 - bi - 1’- naphthyl - 1,2- acenaphthenediol 2 were designed. 1 and 2 can form coordinatoclathrate with various small organic compounds and these inclusion compounds were confirmed by means of IR and powder XRD. The host - guest molar ratios were determined by1H NMR and the Mowing results were found: 1·DMF(1 : 2), 1·DMSO(1 = 2), 1·THF(1 : 2), 1·1,4-dioxane(1 : 1) ,1·pyridine( 1 : 1) ,2·DMF( 1:1) and 2·DMSO( 1:1) . The single crystal structures of newinclusion compounds were determined by X- ray diffraction analysis. The crystal of host(1) -DMF belongs tospace group Pnaa, a =0.9377(1), b = 1.4351(1), c = 4.0463 (3) nm and 1 ?DMSO has space groupPbcn, a = 1.6278(1), b = 1.0751(1), c = 1.4980(1) nm and host(2)·DMF belongs to P21/n, a = 0.9796(1),b = 1.2377(1),c = 2.2344(3)nm;β = 93.02(1)°,? The crystal analysis of freehost(1) showed spacegroup P1, and a = 1.046(1), b = 1.1213(l),c = 1.5496(1 )nm, α = 81.74(1)°,β = 75.78(1)°,γ =89.00(1)°. The effect of rigidity and flexibility of host molecules on inclusion properties were discussed. The selective isolation of the effective component (1,2 - dimethoxy - 4 - 2’ - propenylbenzene) from the volatile oil of Chinese herb Xixin by host(1)was carried out.更多还原
