中文摘要：

模拟卤代过氧化物酶活性中心钒的配位环境设计合成了新的蝎型聚吡唑硼酸盐钒氧化合物VO（HB（3,5-Me2pz）3）（3,5-Me2pz）（HOOCCH2CH2COO）（1）和VO（HB（3,5-Me2pz）3）（3,5-Me2pz）（C5H4NCOO）（2）,通过X射线单晶衍射确定了它们的结构.基于钒（Ⅴ）在水体系中于弱酸性条件下具有催化苯酚红溴化成溴酚蓝的特性,研究了蝎型钒（Ⅳ）氧化合物的催化性能,发现类似条件下蝎型钒（Ⅳ）氧化合物同样存在仿生催化活性,运用分子轨道理论对催化机制进行了分析.

英文摘要：

In order to mimic the active center of the V-HPOs,we designed and synthesized a series of oxovanadium complexes containing poly（pyrazolyl）borate ligands： VO（HB（3,5-Me2pz）3）（3,5-Me2pz）（HOOCCH2CH2COO）（1） and VO（HB（3,5-Me2pz）3）（3,5-Me2pz）（C5H4N-COO）（2）,which were characterized by X-ray single crystal diffraction.Based on the characteristics that vanadium（Ⅴ） complexes catalyze phenol red oxidation of bromide into bromophenol blue in a water system under weak-acid condition,the study on ca-talytic activity about scorpionate oxovanadium（Ⅳ） complexes was preformed.The result shows that the scor-pionate oxovanadium（Ⅳ） complexes exhibit catalytic activity to the extent under the similar conditions.The mechanism of the catalytic reaction was analyzed by molecular orbital theory.
