As an extension to a rational design for the formation of self-assembled coordination cages, the syntheses for very large M4L4 tetrahedra based on a hexadentate 3-fold symmetric ligand (1,3,5-tris(4'-(2' ',3' '-dihydroxybenzamido)phenyl)benzene (H6L2)) are described. Four tetrahedral M4L2(4) assemblies (M = Al(III), Ga(III), In(III), Ti(IV)), with cavity sizes of around 450 A3, have been characterized
作为形成自组装配位笼的合理设计的延伸,基于六齿3倍对称配体(1,3,5-tris(4'-(2'',描述了3''-二羟基苯甲酰胺基)苯基)苯(H6L2)。四个四面体M4L2(4)组件(M = Al(III),Ga(III),In(III),Ti(IV)),腔尺寸约为450 A3的特征已通过元素分析,NMR光谱和高分辨率电喷雾质谱。对于配体1,5-双(2',3'-dihydroxybenzamido)萘(H4L( N))和1,3,5-三(2',3'-二羟基苯甲酰胺基)苯(H6L1)。
