摘要

研究了含有不同数量亚甲基的对称二乙炔 N-芳基氨基甲酸酯分子的朗缪尔-谢弗薄膜的光聚合反应。紫外线照射二乙炔薄膜可使其有效过渡到蓝相聚二乙炔的稳定状态。分子中 CH2 基团的数量会影响单体薄膜向聚合物过渡的效率和聚合物链的共轭长度。薄膜形态的扫描电子显微镜显示，二乙烯分子在基底上以畴状水平排列，其大小取决于分子中 CH2 基团的数量。

Photopolymerization of the Langmuir‒Schaefer Films of Symmetrical Diynylic N-Arylcarbamate Molecules with Different Numbers of СН2 Groups in Spacers

The photopolymerization of Langmuir–Schaefer films of symmetrical diacetylene N-arylcarbamate molecules containing different numbers of methylene groups has been studied. UV irradiation of the diyne films led to their effective transition to the stable state of blue phase polydiacetylene. The number of CH₂ groups in the molecules affected the efficiency of the transition of the monomer film to the polymer and the polymer chain conjugation length. The scanning electron microscopy of the film morphology revealed a horizontal arrangement of the diyne molecules on substrates in the state of domains, the sizes of which depend on the number of CH₂ groups in the molecules.
