5-(2-Methylthio-4-methylpyrimidin-5-yl)penta-2,4-diyn-1-ol was synthesized by asymmetric coupling, and the corresponding diacetylene monomers were also prepared in good yields. These monomers could be dissolved in common organic solvents. The monomers can be polymerized in the solid state using heat, light or γ-radiation. In addition, micro- and macroscopic third-order susceptibilities were measured by the degenerate four-wave mixing (DFWM) method for the yielded polymers.
通过不对称偶联合成了5-(2-甲硫基-4-甲基嘧啶-5-基)五炔-2,4-二醇,并且相应的二炔单体也以良好的产率制备成功。这些单体可以溶解在常见的有机溶剂中。单体可以通过加热、光照或γ辐射在固态下聚合。此外,通过简并四波混合(DFWM)方法测量了所得到聚合物的微观和宏观三阶电磁非线性响应。
