A M2L2 rectangular-shaped metallacycle, obtained by metal-directed self-assembly of a 2-(pyridin-4-ylmethyl)-2,7-diazapyrenium salt and [(en)Pd(NO3)2 (en=ethylenediamine), has been investigated as a molecular receptor for a wide range of aromatic substrates in water. Complexation and catenation of the receptor with selected mono- and polycyclic aromatic substrates produced 1:1 inclusion complexes and [2]catenanes in a highly efficient fashion, as determined by NMR and UV/Vis spectroscopic techniques, as well as single-crystal X-ray crystallography. Furthermore, the thermodynamic and kinetic features of the complexation processes have been analyzed for selected model guests.
通过2-(吡啶-4-基甲基)-2,7-二氮杂芘盐与[(乙二胺)钯(硝酸根)₂](乙二胺 = 乙二胺)的金属导向自组装得到的M2L2矩形金属环，已被研究作为水中多种芳香族底物的分子受体。通过核磁共振（NMR）、紫外可见光谱（UV/Vis）技术以及单晶X射线晶体学确定，该受体与选定的单环和多环芳香族底物的络合和连环化以高效方式产生了1:1包合物和[2]连环烷。此外，还对选定的模型客体的络合过程的热力学和动力学特征进行了分析。
