摘　　要：合成了2-(4-甲氧基苯基)咪唑并[4,5-f]1,10-菲罗啉,采用傅里叶红外光谱、元素分析和X射线单晶衍射表征了化合物的晶体和分子结构。结果表明,目标化合物与相邻2个分子沿晶体c-轴形成2个NH幆N氢键,化合物沿晶体a-轴存在2种π-π堆积作用,这2种作用使目标化合物形成二维的超分子结构。采用琼脂混药法测定了2-(4-甲氧基苯基)咪唑并[4,5-f]1,10-菲罗啉的除草活性,结果证明目标化合物可以选择性的抑制稗草和夏至草的生长,同时促进生菜的生长。2- （4-Methoxyphenyl） imidazole [ 4,5-f] 1,10-phenanthroline was synthesized and characterized by FT-IR, elemental analysis and single crystal X-ray diffraction. The structure analysis revealed that each molecule formed two N-H…N hydrogen bonds with two adjacent molecules. Two types of π-π stacking modes were also observed in the title compound. N-H…N hydrogen bonds and π-π stacking interactions extend along the crystallographic c-axis and a-axis, respectively, which allows the title compound to assemble into a novel two-dimensional supramolecular architecture. The herbicidal activity of the title compound on Echinochloa crusgalli （L.） Beauv. , Lagopsis supine and Lactttca sativa were carried out by the method of grinded plant tissue powder mixed with agar（PPA）. The results show that the growth of Echinochloa crusgalli （L.） Beauv. and Lagopsis supine is inhibited while the growth of Lactuca sativa is promoted by the title compound.
