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

A new supramolecular architecture, {[Zn(FDC)(phen)(H2O)center dot 0.5H(2)O}(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 pi-pi stacking interactions. In addition, the thermal stability and photoluminescence property of 1 were also investigated. (C) 2014 Elsevier B.V. All rights reserved.
