Butadiynes were incorporated into the bolaamphiphile bridge to provide a potential candidate for the topochemical polymerization within the fiber monolayer lipid membranes. Nanoscale fiber was formed from the bolaform butadiyne 1-glucosamide and polymerized to oligodiacetylene-containing fibers. Energy-filtering transmission electron microscopy (EF-TEM) for the unstrained specimens revealed that the gel from the ethyl acetate/n-hexane solution was composed of nanofibers with widths of 6-20 nm. The formation of linear amide hydrogen bond chains can be confirmed by the appearance of the amide N-H and C-to-O double bond stretching bands at 3343, 3060, and 1680/cm, and the N-H deformation band at 1535/cm in Fourier transform infrared spectroscopy.
