摘要: 以Keggin结构的钼磷酸(H3PMo12O40·13H2O)与苯丙氨酸(Phe)为原料,利用一步固相化学反应于室温合成了纳米氨基酸杂多电荷转移配合物(HPhe)3PMo12O40·2H2O,采用元素分析,IR,XRD,TEM,UV和循环伏安法等手段对其进行了结构表征及性质研究.结果表明,标题化合物纳米粒子为均匀的球状,粒径约为30~40nm.该化合物中杂多阴离子部分仍保持Keggin结构,但在钼磷酸与苯丙氨酸之间发生了显著的电荷转移.

Abstract: A nanometer amino acid heteropoly charge-transfer complex was synthesized from Keggin structure phosphomolybdic acid (H3PMo12O40·13H2O) and phenylalanine(Phe) by one step solid state reaction at room temperature. The title compound was characterized by means of elemental analysis, IR, XRD, TEM, UV and CV. The results indicate that the sizes of the compound are in the range of 30-40 nm. The heteropoly anion still remains its Keggin structure in the product molecules. A sizeable electron-transfer interaction occurs between phosphomolybdic acid and phenylalanine. The electrochemical behavior of the compound in 1 mol/L H2SO4 shows that three redox waves correspond to three two-electron processes attributing to the reduction of PMo12O403- . Solid state reaction at room temperature is a convenient synthetic method for nanomaterials and may provide a new path to synthesize nanometer amino acid heteropoly complex.
