 note = {We have synthesized new Ru(II) complexes and viologen derivatives and studied the self-assembling and gelation properties in various organic solvents. These compounds possess a L-lysine derivative as a self-organizing segment. Viologen 1 and 2 formed gels in aromatic solvents (benzene, toluene, nitrobenzene, chlorobenzene), while they precipitated in alcohols. In DMF, DMSO, and chloroform, both viologens have a high solubility and give an isotropic solution. TEM images of samples prepared from these solvents demonstrated that the viologens formed nanometer-scaled assemblies in aromatic solvents and alcohols, but not in chloroform. In toluene, 1 and 2 had a nanofiber with ca. 250- 700 nm width and nanoribbon with ca. 300- 400 nm width, formed by entangling of fine fibers (ca. 30 -IOO nm width) or ribbons (ca. 70-200 nm width). It is noteworthy that the viologens created different nanostructures; a fibrous structure for 1 and a ribbon structure for 2. On the other hand, Ru2 has a gelation ability for some aromatic solvents, but Ru1 gave isotropic solutions for these solvents. The minimum gelation concentration of Ru2 is 2 mg/ml for benzene and 4 mg/ml for toluene. The TEM images of Ru1 and Ru2 prepared from toluene showed that Ru1 and Ru2 formed a nanofiber structure. Ru2 created the network by entanglement of fine fibers , and such a hierarchical network structure is responsible for the gelation behavior of Ru2. In contrast, Ru1 forms a helical structure., Article, 先進ファイバー工学研究教育拠点研究成果報告書 10: 29-30(2004)},
