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.

通过互补的客体插层降低电活性金属-有机骨架的带隙

一种新的蜂窝状电活性金属-有机骨架（MOF）由具有两个末端水杨酸基团的缺电子萘二酰亚胺（NDI）配体构建而成。沿壁堆积的NDI配体之间的富电子平面四硫富瓦烯（TTF）客体的π插入使材料的电子能带隙降低了约1。1 eV。通过客体介导的π-供体/受体叠层改善的电子离域作用归因于掺杂材料的带隙减小，这预示了改善的电导率。
