摘要：利用水滑石类化合物层间阴离子的可交换性，采用共沉淀的方法，实现了含有磺酸基团的的金属磺化四苯基卟啉（MTPPS，M=Co，Fe，Mn）和含有两个羧酸基团的次卟啉（DP）与层板间含有不同金属离子的水滑石类化合物（LDHs）的插层组装，制备了一系列新型“有机-无机”复合材料，通过XRD、FT-IR及UV-Vis等表征方法对其结构进行了表征。并考察了各合成参数对制备的材料的影响。研究结果表明：采用共沉淀法可以实现两类卟啉化合物与类水滑石的插层组装。合成MTPPS-M2+/M3+-LDHs体系的pH值，M2+/M3+的种类及比值，MTPPS中心的金属离子种类等都对材料的结构具有重要影响；合成DP-M2+/M3+-LDHs材料时，在一定范围内，pH值和M2+/M3+对合成材料的影响较小。

Abstact：In the thesis, a series of inorganic-organic hybrids have been prepared byintercalation of metal complexes of 5,10,15,20-tetrakis(4-sulfonatophenyl) porphyrins (MTPPS, M=Co, Fe, Mn) and deuteroporphyrins (DP) into layered double hydroxides (LDHs) by coprecipitation method. The resulting materials were characterized by powder X-ray diffraction, UV-Vis and FTIR spectroscopies showing the intercalation of porphyrins between the LDHs layers. The effects of reaction condtions on the synthesized materials have also been studied. In the preparation of MTPPS-M2+/M3+-LDHs, the reaction pH, the kinds and ratio of M2+/M3+ and the complexed metals in the center of porphyrins have important influence on the structure of the materials, while in the DP-M2+/M3+-LDHs, the reaction condtions have less influence.
