摘要:利用水滑石類化合物層間陰離子的可交換性,采用共沉淀的方法,實現了含有磺酸基團的的金屬磺化四苯基卟啉(MTPPS,M=Co,Fe,Mn)和含有兩個羧酸基團的次卟啉(DP)與層板間含有不同金屬離子的水滑石類化合物(LDHs)的插層組裝,制備了一系列新型“有機-無機”復合材料,通過XRD、FT-IR及UV-Vis等表征方法對其結構進行了表征。并考察了各合成參數對制備的材料的影響。研究結果表明:采用共沉淀法可以實現兩類卟啉化合物與類水滑石的插層組裝。合成MTPPS-M2+/M3+-LDHs體系的pH值,M2+/M3+的種類及比值,MTPPS中心的金屬離子種類等都對材料的結構具有重要影響;合成DP-M2+/M3+-LDHs材料時,在一定范圍內,pH值和M2+/M3+對合成材料的影響較小。 關鍵詞:金屬卟啉;類水滑石;插層組裝
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. Key words:Metalloporphyrin; Hydrotalcite-like compounds; Intercalation
