Abstract

Two new coordination polymers (compounds 1 and 2) based on the use of a V-shaped ligand L (9,9-bis(4-carboxyphenyl)fluorene) combined with Cu(NO₃)₂ or Zn(NO₃)₂ were synthesized and structurally characterized by single-crystal X-ray diffraction. These compounds add to the list of very few examples of reported CPs derived from ligands with a fluorene core. X-ray diffraction analysis revealed the structures of the compounds; 2D (1) and robust 3D (2) structures were reported, and their sorption and emission properties were analysed. Additionally, it was possible to isolate the following compounds as side products: compound 4, a 2D compound that is isomorphous to 1, and compound 3, a polymorph of 1.
