Abstract

Recently, we found that alkylhydrazide derivatives, which are commercially available and low cost reagents, formed organogels in various organic solvents having dielectric constants ranging from 2 to 66. We also found that organogels comprised of mixed alkylhydrazide derivatives with different alkyl chain lengths as low-molecular-weight organogelators showed thixotropic behaviors, whereas organogels comprised of a single alkylhydrazide derivative did not show such behaviors. The transparency and mechanical properties of the mixed organogels were enhanced. This mixing enhancement for organogelators might be attributed to an improved network of closer and finer fibers as compared with that in a one-component system.
