Compounds <b>1</b> and <b>2</b> are 1D coordination polymers, while compounds <b>3</b>–<b>8</b> are 2D coordination polymers. All compounds were characterized by spectroscopic and X-ray diffraction methods of analysis. The solvent uptakes and stabilities to the guest evacuation were studied and compared for 1D and 2D coordination networks. The de-solvated forms revealed a significant increase of emission in comparison with the as-synthesized crystals. |
