摘要
以4-氨基安替比林与2-(4-甲基吡啶)-2-异烟酸醛缩合反应得到新型安替比林衍生物(E)-1,5-二甲基-4-((2-(4-甲基吡啶-2-基)吡啶-4-基)亚甲基氨基)-2-苯基-1,2-二氢吡唑-3-酮(L),并对其光学、金属离子选择性识别性能和单晶结构进行了研究。发现L在水-乙醇(9∶1,V/V)溶液中,能选择性比色和肉眼识别Fe~(2+),且受常见金属离子的干扰较小。用Job法得到Fe~(2+)与L的化学计量比为1∶3([FeL_3]~(2+)),配合物的缔合常数为3.70×1021 L3·mol-3,检测限为0.094μmol·L~(-1)。结果表明,化学传感器L可作为一种有选择性、灵敏的Fe~(2+)比色传感器。
        An aminoantipyrine based chemosensor,(E)-1,5-dimethyl-4-((2-(4-methylpyridin-2-yl)pyridin-4-yl)methyleneamino)-2-phenyl-1,2-dihydropyrazol-3-one(L), derived from 4-aminoantipyrine and 2-(4-methylpyridin-2-yl) isonicotinaldehyde, was synthesized and the optical and metal sensing properties were investigated. The chemosensor L showed a selective colorimetric sensing ability for Fe~(2+)by changing colors from pale yellow to deep red in water-ethanol(9∶1, V/V) medium, which facilitates the ‘naked-eye' recognition of Fe~(2+)from other examined metal ions. The complex stoichiometry of Fe~(2+)to L(1∶3, [FeL_3]~(2+)) was obtained by Job′s method. The association constant was determined to be 3.70×1021 L3·mol~(-3). The present results indicate that the chemosensor L could be used as a selective, sensitive colorimetric sensor for Fe~(2+). CCDC: 1817471, L.
