UNAM-1: a robust CuI and CuII containing 3D-hydrogen-bonded framework with permanent porosity and reversible SO2 sorption

The construction of hydrogen-bonded frameworks (HBFs) that express permanent porosity and functionality is challenging due to the delicateness of hydrogen bonds. We present UNAM-1, a robust 3D-HBF fully sustained by charge-assisted H-bonds between [CuIICu12I(HL)12]10− and [Me2NH2]+ units, which disp...

Zusammenfassung:The construction of hydrogen-bonded frameworks (HBFs) that express permanent porosity and functionality is challenging due to the delicateness of hydrogen bonds. We present UNAM-1, a robust 3D-HBF fully sustained by charge-assisted H-bonds between [CuIICu12I(HL)12]10− and [Me2NH2]+ units, which displays a surface area of 522 m2 g−1 and reversibly adsorbs SO2 (3.5 mmol g−1).
