摘　　要：Chiral Schiff-base ligand L was synthesized through six steps in good overall yield from readily available 2-tert-butylphenol and was used to construct one chiral porous metal-metallosalen framework,[Zn5(μ3-OH)2(ZnL)4(H2O)2]·18H2O(1,L=5′,5″-(1E,1′E)-(1R,2R)-cyclohexane-1,2-diylbis(azan-1-yl-1-ylidene)bis(methan-1-yl-1-ylidene)bis(3′-tert-butyl-4′-hydroxybiphenyl-4-carboxylic acid),under mild reaction conditions.1 was characterized by IR,TGA,CD,UV,PL,single-crystal and powder X-ray crystallography.The structure of 1 displays a 3-fold interpenetrating 3D framework with 1D channel of 1.14 nm×0.58nm and imparts unique Zn(salen)units on the surface of the pore,in which(ZnL)2dimer acts as multi-functionlized metalloligand.1 is thermally robust with network decomposition temperature of 400oC and it also exhibits strong photoluminescence in the visible region.Chiral Schiff-base ligand L was synthesized through six steps in good overall yield from readily available 2-tert-butylphenol and was used to construct one chiral porous metal-metallosalen framework,[Zn5（μ3-OH）2（ZnL）4（H2O）2]·18H2O（1,L=5′,5″-（1E,1′E）-（1R,2R）-cyclohexane-1,2-diylbis（azan-1-yl-1-ylidene）bis（methan-1-yl-1-ylidene）bis（3′-tert-butyl-4′-hydroxybiphenyl-4-carboxylic acid）,under mild reaction conditions.1 was characterized by IR,TGA,CD,UV,PL,single-crystal and powder X-ray crystallography.The structure of 1 displays a 3-fold interpenetrating 3D framework with 1D channel of 1.14 nm×0.58nm and imparts unique Zn（salen）units on the surface of the pore,in which（ZnL）2dimer acts as multi-functionlized metalloligand.1 is thermally robust with network decomposition temperature of 400oC and it also exhibits strong photoluminescence in the visible region.
