摘要
主要论述了MNA与MBD的合成方法与结构测定。应用新方法制备MNA化合物,副产物少,纯化简单,产率高。MBD二乙炔单体苯/乙醚混合溶剂中培育单晶,经热作用下的固态品相聚合制备高分子单晶,聚合过程存在诱导效应和自加速现象。上述化合物分子结构属于含给体基团与受体基团的π电子共轭体系。它们有着较大的非线性极化系数,在非线性光学应用中有广阔的前景。
The syntheses and structural determinations of MNA and MBD are reported . The new method of preparation for MNA compounds shows a high yield, fewer by-products and easy purification. with the solid-state polymerization by - thermal annealing , diacetylenic monomer MBD single crystal , which crystallizes in a benzene /ether solvent, is converted to polymeric single crystal. In the polymerization process, there exist induced eflFects and the phenomenon of auto - acceleration. The molecular structure of the compounds mentioned above belong to π electron conjugated system with donor and acceptor groups . They demonstrate high second - order nonlinear optical hyperpolarizability values and show vast vistas in the nonlinear optics .
