The synthesis of metal–organic frameworks with large three‐dimensional channels that are permanently porous and chemically stable offers new opportunities in areas such as catalysis and separation. Two linkers (L1=4,4′,4′′,4′′′‐([1,1′‐biphenyl]‐3,3′,5,5′‐tetrayltetrakis(ethyne‐2,1‐diyl)) tetrabenzoic acid, L2=4,4′,4′′,4′′′‐(pyrene‐1,3,6,8‐tetrayltetrakis(ethyne‐2,1‐diyl))tetrabenzoic acid) were used
具有大型三维通道,永久多孔且化学稳定的金属有机骨架的合成为催化和分离等领域提供了新的机遇。两个接头(L1 = 4,4',4'',4'''-([[1,1'-联苯] -3,3',5,5'-四基四(乙炔-2,1-二基))四苯甲酸,L2 = 4,4',4'',4'''-(py-1,3,6,8-四基四(乙炔-2,1-二基))四苯甲酸)具有相同的连通性和尺寸,但具有明显的扭转弹性。由此形成了固溶体材料[Zr 6 O 4(OH)4(L1)2.6(L2)0.4 ]⋅(溶剂)x,该材料具有三维晶体永久孔隙率,表面积超过4000 m 2个 g -1浸入水中后仍然存在。对于由单独的单个接头制成的同构相,这些属性是不可访问的。
