芳香酸不同取代基调控的氢键有机框架材料的合成与结构
Synthesis and structure of hydrogen-bonded organic frameworks regulated by aromatic acids with different substituents
摘要
Abstract
[H2dap]2[pa]·5H2O(Complex 1)with phthalic acid(H2pa)as the guest and[H2dap]2[da](Complex 2)with 4,5-dichlorophthalic acid(H2da)as guest were synthesized by hydrothermal method using 2,6-diaminopurine(Hdap)as host.Two complexes were characterized by single-crystal and power X-ray diffraction,elemental analysis,FT-IR spectrum.The results showed that:① Complex 1 crystalizes in orthorhombic Pbca space group,and Complex 2 crystalizes in monoclinic C2/c space group;② The different types of hydrogen bonds between 2,6-diaminopurine and aromatic acids are mainly due to the different substituents of two aromatic acids;③ The participation of water molecules in Complex 1 not only increases the types of hydro-gen bonds,but also consolidates the entire hydrogen-bonded organic frameworks stucture.关键词
