摘　　要：本文通过相应的吡咯和丙二酰氯的缩合,以BF3·Et2O处理,首次合成了含芳基的二吡咯二酮二氟硼络合物(BONEPYs)。研究表明通过调节氢键,BONEPYs与F^-先形成三配位络合物,后变成五配位络合物。实验和量化计算表明,BONEPYs五配位络合物相对能量更低,对F^-高度敏感。因此,合成的BONEPYs可作为检测F^-更有效的探针。The aryl-containing dipyrrolyldiketone difluoroboron complexes(BONEPYs)were developed for the first time by the condensation of the corresponding pyrrole and malonyl chloride,followed by treatment with BF3·OEt2.Studies showed that BONEPY and F^- first formed a tri-coordination complex by adjusting the hydrogen bond,which gradually became a penta-coordination complex.Experimental and theoretical results showed that the BONEPYs pentacoordinate complex had lower relative energy and was highly sensitive to F^-.Therefore,BONEPYs as an efficient probe could detect F^-.
