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.
