The amphiphilic diacetylenes with directly-bound aromatic substituents, i. e. 27-aryl-24,26-heptacosadiyn-1-ols and -diynoic acids, were synthesized and the solid-state polymerization of these compounds upon γ-ray and UV irradiation was investigated. More than half of the compounds synthesized are polymerizable because the packing effect of the methylene chains makes the diacetylene moieties align into polymerizable stack. It is found that the bulkiness of hydrophilic and hydrophobic ends was an impotant factor for the polymerizability of this series of compounds.
含有直接连接芳香取代基的两性二炔化合物,即27-芳基-24,26-七十炔-1-醇和-二炔酸,已被合成,并研究了这些化合物在γ射线和紫外线照射下的固态聚合。合成的化合物中超过一半是可聚合的,因为亚甲基链的堆积效应使得二炔基团排列成可聚合的堆叠。研究发现,亲
