Unique 1D → 3D polycatenated architecture constructing from 1D single-armed chains incorporating with two rigid aromatic coligands

• A unique 1D → 3D inclined polycatenated net
• The crosslinking Zn(II)-network drived by ππ stacking
• Two of sets of 1D single-armed polymeric chains oriented in different directions

A new supramolecular architecture, {[Zn(FDC)(phen)(H2O)]·0.5H2O}n (1), was obtained from mixed rigid ligands [9-fluorenone-2,7-dicarboxylic acid (H2FDC), 1,10-phenanthroline (phen)] and zinc(II) nitrate under hydrothermal reactions, which displays a charming 1D → 3D polycatenated motif based on 1D single-armed polymeric chains via powerful ππ stacking interactions. In addition, the thermal stability and photoluminescence property of 1 were also investigated.

A unique entangling Zn(II)-network shows a self-catenated ππ stacking topological structure, which can be viewed as the crosslink of 1D → 3D inclined polycatenated framework consisting of two of sets of 1D single-armed polymeric chains.Figure optionsDownload as PowerPoint slide
