Hexagonal hexaminophenyl benzene (HAPB), tetragonal tetrakis(4-aminophenyl) ethane (ETTA) and trigonal 1,3,5-tris( p-formylphenyl)benzene (TFPB) were all joined together by imine link-ages to yield a 2D porous covalent organic framework with unprece-dented tth topology, termed COF-346. Unlike the 5 simple existing 2D topologies reported in COFs, COF-346 has 3 kind of vertices and 2 kind of edges and is constructed with linkers of 3 kinds of connectivity, and thus represents a higher degree of complexity in COF structures. The success in crystallizing COF-346 was based on precisely chosen geometry and metrics of the linkers and error correction offered by dynamic imine formation. We also report two additional related COFs: a crystalline, porous COF, termed COF-360 with a rare kgd topology, as well as the first crystalline, porous COF with defected tth topology, termed COF-340.

多元共价有机骨架的网状合成

六方六氨基苯基苯（HAPB）、四方四（4-氨基苯基）乙烷（ETTA）和三方1,3,5-三（对甲酰基苯基）苯（TFPB）都通过亚胺键连接在一起，产生二维多孔具有前所未有的 tth 拓扑结构的共价有机框架，称为 COF-346。与 COF 中报道的 5 种简单的现有 2D 拓扑不同，COF-346 具有 3 种顶点和 2 种边，并由 3 种连接的链接器构成，因此在 COF 结构中代表了更高程度的复杂性。COF-346 结晶的成功基于精确选择的几何形状和连接器的度量以及动态亚胺形成提供的纠错。我们还报告了另外两个相关的 COF：一种结晶的多孔 COF，称为 COF-360，具有罕见的 kgd 拓扑结构，以及第一个晶体，
