通过扫描隧道显微镜(STM)观察到1，3，5-三(10-羧基十二氧基)苯(TcDB)模板表面桥联的配位二聚体络合物的形成。本文报道了四苯基卟啉锌(ZnTPP)、酞菁锌(ZnPc)及其混合物分子膜的扫描隧道显微镜(STM)图像。ZnTPP和ZnPc可以自发形成高度有序的结构，摩尔比为1：1，这与单独的ZnPc不同。提出了以轴向配体桥联的配位双分子络合物，简称为ZnPc-DPP-ZnTPP和ZnPc-DPE-ZnPc，并对其表面结构进行了比较。ZnPc和ZnTPP可以通过轴向配体DPP连接，并在表面外形成组装结构。得到了两种全新结构的ZnPc-DPE-ZnPc络合物阵列。这些桥联杂化化合物提供了一个基于非共价相互作用配位的自组织晶体设计的例子。
The formation of coordinated dimeric complexes bridged by axial ligands on surface is observed with the help of a 1,3,5-tris(10-carboxydecyloxy)benzene (TCDB) template through scanning tunneling microscopy (STM). STM images of molecular adlayers of zinc tetraphenylporphyrin (ZnTPP), zinc phthalocyanine (ZnPc), and their mixture are reported. ZnTPP and ZnPc can spontaneously form highly an ordered structure with a 1:1 molar ratio, which is different from that of individual ZnPc. The coordinated bimolecular complexes bridged with axial ligands, simply as ZnPc–DPP–ZnTPP and ZnPc–DPE–ZnPc, are presented and the corresponding surface structures are compared. ZnPc and ZnTPP can be connected by an axial ligand DPP and formed assembled structures out of surface. Two types of arrays with entirely new structure are obtained for the ZnPc–DPE–ZnPc complex. These bridged hybrid complexes provide an example of design of self-organized crystals on the basis of coordination through non-covalent interactions.
