多主题环三戊四烯型配体形成的配位聚合物综述。环三戊四烯（Cyclotriveratrylene， CTV）是一种具有碗状三苯并[a，d，g]环三戊三烯支架的分子宿主。具有n给体和o给体基团的三足和六足配体已经被开发出来，这些配体形成了一系列与过渡金属的配位链、二维和三维配位网络。这些配体是分子宿主，因此有可能形成具有宿主特异性和晶格客结合位点的材料。这篇重点文章将讨论配体的主客体性质如何影响ctv型配体形成诸如腔内客体结合、碗中碗堆叠和握手包合基序等材料的能力，这些材料有效地阻断了宿主特异性结合位点。一系列具有分层客体结合位点的配位聚合物材料是由ctv型配体形成的，最常见的是存在配位胶囊或笼状网络，或者配位体在网络中交替呈碗状或碗状排列导致管状结构。
A review of coordination polymers formed using multi-topic cyclotriveratrylene-type ligands. Cyclotriveratrylene (CTV) is a molecular host with a bowl-shaped tribenzo[a,d,g]cyclononatriene scaffold. Tripodal and hexapodal ligands with N-donor and O-donor groups have been developed and these form a range of coordination chains, 2D and 3D coordination networks with transition metals. Such ligands are molecular hosts so there is potential to form materials with both host-specific and lattice guest-binding sites. This highlight article will discuss how the host–guest properties of the ligands can compromise the ability of CTV-type ligands to form such materials as intracavity guest binding, bowl-in-bowl stacking and hand-shake inclusion motifs effectively block the host-specific binding site. A range of coordination polymer materials which do feature hierarchical guest-binding sites are formed from CTV-type ligands, most commonly where there are networks of coordination capsules or cage, or where alternating bowl-up, bowl-down arrangements of ligands within networks leads to tubular structures.
