Embodiment 1

[0057] A solution of 10 milliliters of anhydrous dichloromethane containing 2.96 grams of octadecylamine (reagents obtained from Kagaku Co., Ltd.) was charged into the reaction vessel, and 10 milliliters of dimethylacetamide (DMAc) was mixed with a dropping funnel. was added to 4.83 g of an ethyl acetate solution containing 27% by weight of triphenylmethane triisocyanate (TPMTI) (“DISMODULE RE” (trade name), available from Sumitomo Bayer Urethane Co. Ltd.; NCO equivalent: 441). The solution was slowly added dropwise to the reaction vessel and stirred at room temperature for 1 hour. By observing the infrared spectrum (KBr method) at 2230 cm -1 The end point of the reaction was determined by the disappearance of the NCO group. The resulting reaction mixture was added to a large amount of distilled water to obtain a precipitate. The resulting precipitate was purified by column chromatography to obtain the target product. As a result, it was confirmed that the amount of the tar...

Abstract

A triphenylmethane derivative represented by the general formula (1), an organic gallant containing the derivative, an organic gel, and an organic fiber. Although the triphenylmethane derivative is a low-molecular compound, it has the ability to cause, when added in a relatively small amount, various organic solvents to gel. The organic gel obtained is useful as a chemomechanical system material usable at high temperatures, impact / vibration-absorbing material, medicine base, sustained-drug-release material, silicone oil gel for electrolytic-liquid solidification or for cosmetics, etc. Organic nanofibers can be produced from the triphenylmethane derivative through a simple process. The nanofibers are usable in applications such as a wiring material for electronic devices, separation membrane for nanoscale substances, photocatalyst with high efficiency, and culture medium for regenerative medicine and filter for biochemical hazard prevention both employing a nonwoven nanofiber fabric.

Description

technical field [0001] The present invention relates to novel triphenylmethane derivatives, organic gelling agents, organic gels and organic fibers containing the triphenylmethane derivatives. The triphenylmethane derivative has the ability to gel various organic solvents under heating conditions and to easily produce organic nanofibers. Background technique [0002] Gel means that the colloidal particles in the colloidal solution condense under certain conditions to form a network structure and enclose the liquid in it, which loses or basically loses fluidity. Depending on whether the solvent as a gel component is water or an organic solvent, gels are generally classified into hydrogels and organic gels. [0003] Organogels containing organic solvents with boiling points higher than water as their components can be used for applications where hydrogels cannot, such as shock and vibration absorbing materials that can be used under high temperature conditions, sustained drug...
