文摘
A new microporous hydrogen-bonded organic framework (HOF) based on a cobalt(II) porphyrin, namely, Co(II) 5,10,15,20-tetra(4-(4-acetateethyl)phenoxy)phenylporphyrin (1), has been synthesized and structurally characterized. Single crystal X-ray diffraction analysis reveals that porphyrin molecules connect each other by intermolecular hydrogen bonds to form 2D layer, and the 2D layer further links though 蟺路路路蟺 interactions to form 3D supramolecular structure, exhibiting one kind of micropore with 3.98 脳 6.47 脜2. The HOF of 1 exhibits not only a permanent porosity with the Langmuir surface areas of 158.79 m2路g鈥?, and the Brunauer鈥揈mmett鈥揟eller surface areas of 97.70 m2路g鈥?, but also, more importantly, high catalytic efficiency and selectivity for oxidation of ethylbenzene to acetophenone in quantitative 83.1% yield.
