摘　　要：A series of dibutyltin complexes,(Bu_(2)Sn)_(2)L,[(Bu_(2)Sn)_(2)L]3 and H_(2)LSnBu_(2),were synthesized by microwave-assisted methanolic solvothermal method,where H4L is[_(2)-(OH)-R-ArCH=NNH]_(2)CX,and X=O,R=4-NEt_(2)(Tl),5-Br(T_(2));X=S,R=H(T3);R=5-Br(T4).Their structures were characterized by elemental analysis,IR and(^(1)H,^(13)C)-NMR spectra.The molecular structure of T_(2) was confirmed by X-ray diffraction.The crystal of T_(2) belongs to monoclinic system,space group la.Five-coordinated distorted triangular bipyramids and six-coordinated distorted octahedral configurations were formed by the coordination of oxygen and nitrogen atoms of ligand with two dibutyltins,thus forming a trimeric hexanuclear butyltin complex by the cross coordination of three units(Bu_(2)Sn)_(2)L with enol imines.The T_(2) and T4 exhibit fluorescence emission in DMF solvents and DMF-water mixture.The fluorescence intensity of T_(2)-DMF-H_(2)0 system decreases almost linearly with the increase of water volume fraction(WVF).The aggregation fluorescence enhancement effect of T4-DMF-H_(2)0 solution system increases with the increase of WVF at the range of 0-_(2)0%WVF.When WVF is more than _(2)0%,the fluorescence intensity decreases with the increase of WVF.In addition,T1〜T4 have broad growth activities on target plants,such as Portulaca oleracea L.,Amaranthus spinosus L.,Cassia tora L.,Brassica campestris L.ssp.chinensis var.utilis Tsen et Lee,and Amaranthus tricolor L.,and can be used as a candidate herbicide for further research.
