摘　　要：A novel tolane 4-methoxy-4'-nitro-diphenyl-acetylene (MONA) has been prepared quantitatively by reacting cuprous p-methoxy phenyl-acetylene with p-iodonitrobenzene. A single crystal of the Moan was grown by solution growth method. The crystal was then characterized by X-ray diffraction structure analysis and second-harmonic generation(SHG)investigation. Polymorphous crystal forms of the MONA were grown from different solvents having different nonlinear optical properties depending on their different crystal structures. The relationship between the crystal growth and crystal structure is discusse.用对甲氧基苯乙炔铜与对碘硝基苯反应，定量地合成了对甲氧基对硝基二苯基乙炔，用溶剂法生长了它们的单晶．用X射线衍射结构分析和测定SHG效应方法研究了这些晶体，发现从不同的溶剂中生长的单晶体具有不同的晶体结构，并且具有不同的光学性质．讨论了晶体生长、晶体结构与其光学性质的相互关系．
