Abstract Three homochiral metal–organic frameworks ( MOF s) based on enantiopure chiral ligand: (R)-2,2’-dimethoxy-5,5′,6,6′,7,7′,8,8′-octahydro-1,1′-binaphthyl-3,3′-dicarboxylic acid ( H 2 L ), namely Cd( L )(Py) 3 1 , Cu( L )(Py) 3 2 , Na[Cd( L )( LH )] · 2.5H 2 O 3 (Py = pyridine), were firstly synthesized, under solvothermal reactions. X-ray single-crystal diffraction studies reveal that 1 and
摘要 基于对映体纯手性配体的三种同手性金属-有机骨架 (MOF s):(R)-2,2'-二甲氧基-5,5',6,6',7,7',8,8'-octahydro- 1,1'-联萘-3,3'-二羧酸(H 2 L ),即Cd( L )(Py) 3 1 、Cu( L )(Py) 3 2 、Na[Cd( L )( LH ) ] · 2.5H 2 O 3 (Py = 吡啶),首先在溶剂热反应下合成。X射线单晶衍射研究表明,1和2采用一维(1D)无限螺旋结构,而3采用沿a轴采用ABAB偏移堆叠模式的二维手性骨架结构。热重分析 (TGA) 显示 3 在 330 °C 下是热稳定的,这对于同手性 MOF 来说是罕见的。
