Synthesis of a novel two dimensional BINOL metal-organic framework

以2-羟基-6-萘甲酸为原料,经过酯化、偶合、水解制得配体1,1'-联萘-2,2'-二羟基-6,6'-二甲酸,并以扩散法合成了一种新型二维BINOL-Sr金属有机框架(MOF(1)).配合物为三斜晶系,P-1空间群,晶胞参数:a=0.787 5(4)nm,b=1.242 1(8)nm,c=1.336 4(9)nm,α=114.64(2)°,β=98.644(15)°,γ=96.093(19)°,V=1.153 8(13)nm3,Z=2,R_1=0.049 6,wR_2=0.120 6.

1,1'-binaphthyl-2,2'-dihydroxy-6,6'-dicarboxylic acid was synthesized from 2-hydroxy-6-naphthoic acid by esterification,coupling and hydrolysis.A new type of two-dimensional BINOL-Sr metal-organic framework(MOF(1))was synthesized by diffusion method.The complex crystalized in triclinic,P-1,with a=0.787 5(4)nm,b=1.242 1(8)nm,c=1.336 4(9)nm,α=114.64(2)°,β=98.644(15)°,γ=96.093(19)°,V=1.153 8(13)nm 3,Z=2,R 1=0.049 6,wR 2=0.120 6.
