Abstract: The 1,5-asymmetric disubstituted carbohydrazide ligands were prepared by condensation of carbohy-drazide with salicylaldehyde and then with vanillin. The butyltin complex B1 based on the 1,5-disubstituted carbohydrazide and the complex B2 containing salicylaldehyde azine were obtained by solvothermal reaction of n-BuSnCl3 with the ligand in methanol environments, which have been structurally characterized by elemental analysis, IR and 1H, 13C, 119Sn NMR spectra. The crystal of complex B1 belongs to monoclinic system, space group P21/n, and the crystal of complex B2 belongs to triclinic system, space group P1. The Sn atom is six-coordinated with distorted octahedral geometry by O, N atoms from ligand, C atom of butyl and two Cl atoms. The complex B1 had good fluorescence properties in the DMF-H2O solvents, and the water content in the 0~10%(V/V) range had aggregation induced emission enhancement(AIE). When the water content was more than 10%, the fluorescence intensity decreased with the increase of water volume fraction, and finally was quenched. The ligand and its butyltin complex B1 have the effect of growth on the 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. The ligand has a good inhibitory effect on the growth of Portulaca oleracea L. and Amaranthus spinosus L., and the complex has selective inhibition on the growth of Cassia tora L., which can be used as a candidate compound for Cassia tora L. herbicide. |
