| 摘要 |
In accordance with the present invention, there are provided a triphenylmethane derivative represented by the following general formula (1), an organic gelling agent containing the triphenylmethane derivative, an organic gel and an organic fiber. The triphenylmethane derivatives of the present invention can exhibit a capability of gelling various organic solvents even when used in a small amount notwithstanding these derivatives are low-molecular compounds. The resultant organic gel is useful as materials usable under a high-temperature condition such as chemomechanical system materials, impact and vibration absorbing materials, drug base materials, controlled drug-release materials, and silicone oil gels for solidification of electrolytic solutions and for cosmetics. In addition, an organic nanofiber can be produced from the triphenylmethane derivative by a simple process. The organic nanofiber can be applied to wiring materials for electronic devices, separation membranes for nano-scale substances, high-efficiency photocatalysts, and culture media for regenerative medical treatments or filters for preventing biochemical hazards utilizing a nonwoven fabric (nano-fabric) made of nanofiber. |
