Popis: | The Langmuir−Blodgett (LB) method was applied to low molecular weight organogelator N-[N-(6-hydroxyhexyl)-3-carbamoylpropyl]-3,4,5-tris(dodecyloxy)benzamide (1) to form molecular-assembly fibers on a solid substrate. Molecule 1 formed a stable monolayer up to 40 mN/m at the air−water interface. The monolayer was transferred onto a mica surface at 35 mN/m. In the transferred film, fibrous structures with typical dimensions of 1.2 nm (height) × 50−100 nm (width) × 5−10 μm (length) were observed by atomic force microscopy. These structures were ordered in specific directions, reflecting the C6 surface crystal symmetry of mica. Lateral modulation frictional force microscope measurements revealed that the fibrous structures had high crystallinity and that the surface groups were hydrophilic. These results enabled us to construct functional fibers by introducing functional units into the hydrophilic part of molecule 1. N-[N-(6-Aminohexyl)-3-carbamoylpropyl]-3,4,5-tris(dodecyloxy)benzamide hydrochloride (2) has ... |
