A new honeycomb-shaped electroactive metal-organic framework (MOF) has been constructed from an electron deficient naphthalenediimide (NDI) ligand equipped with two terminal salicylic acid groups. π-Intercalation of electron-rich planar tetrathiafulvalene (TTF) guests between the NDI ligands stacked along the walls lowers the electronic band gap of the material by ca. 1 eV. An improved electron delocalization through the guest-mediated π-donor/acceptor stacks is attributed to the diminished band gap of the doped material, which forecasts an improved electrical conductivity.
一种新型的蜂窝状电活性金属有机骨架（MOF）由一个电子缺失的萘二酰亚胺（NDI）配体构建而成，该配体带有两个末端水杨酸基团。电子富平面四硫富瓦烯（TTF）客体在沿着壁堆积的 NDI 配体之间的π-插入作用使材料的电子能带隙降低了约 1 eV。通过客体介导的π-供体/受体堆积体来改善电子离域作用归因于掺杂材料的能带隙减小，这预示着电导率的提高。
