对苯二磺酸和1，3，5-苯三磺酸以有效的和可放大的两步方案从相应的溴苯衍生物制备。这些酸类似于对苯二甲酸和均苯三酸用于形成具有铜（II）中心的金属有机框架。由于磺酸的酸性增强，弱碱性孔雀石可用作无机前驱体材料。在约100 ° C下脱水后，无水骨架相对于通常已知的羧酸酯MOF表现出显著增加的热稳定性（高达400 ° C）。((C)Wiley-VCH Verlag GmbH & Co. KGaA，69451魏因海姆，德国，2009）
p-Benzenedisulfonic acid and 1,3,5-benzenetrisulfonic acid are prepared in an efficient and scalable two-step protocol from respective bromobenzene derivatives. These acids are used in analogy to terephthalic and trimesic acid for the formation of metal-organic frameworks with copper(II) centers. Due to the enhanced acidity of sulfonic acids, weakly basic malachite can be used as inorganic precursor material. After dehydration at about 100 degrees C, the anhydrous frameworks exhibit significantly increased thermal stability (up to 400 degrees C) relative to the commonly known carboxylate MOFs.
