Compositions of oligoanilines with higher purity, methods of making and using thereof, are provided. The compositions are produced in large scale with larger yield using simple purification techniques such as washing. Methods have been developed that allow large scale synthesis of oligoaniline compounds with the following benefits: (i) higher purity; (ii) larger yield of oligoaniline compounds; (iii) simple purification that does not require complicated techniques such as liquid chromatograph; (iv) lower cost; and (v) full characterization. The highly pure oligoaniline compositions can be used as reducing or oxidizing agent in a redox reaction. The oligoaniline compositions have colors and can be used as dyes, i.e. redox active dyes in a redox reaction, as intermediates for the development of conductive elastomers, or as catalysts.

Synthesis of organic compounds that has chirality is an important technique in the fields of pharmaceuticals, agrichemicals, health foods and the like. However, raw materials of a catalyst used for the synthesis of such compounds are expensive, and the synthesis needs many steps, so that it is difficult to reduce the cost. Linking a catalyst center to a polymer chain or a resin through an organic group enables to use the catalyst repeatedly and produce a chiral compound at low cost.

One purpose of the present invention is to provide a liquid-crystal compound which exhibits liquid crystallinity at low temperatures. Another purpose of the present invention is to provide a thermally responsive material which exhibits liquid crystallinity and rubber elasticity at low temperatures (around room temperature) ever, though a large amount of a liquid-crystal compound is contained therein, and a method for producing this thermally responsive material. A liquid-crystal compound according to the present invention is obtained by adding an alkylene oxide and/or styrene oxide to a mesogenic group-containing compound that has an active hydrogen group.

This invention discloses a type of 1,8-bis(Schiff base)-p-menthane derivatives as well as their preparation method and applications. The reaction of 1,8-diamino-p-menthane with a substituted benzaldehyde was carried out in a polar organic solvent at 0 C.-75 C. for 1-48 h. After the completion of the reaction, part of the solvent was distilled off to perform recrystallization to get a 1,8-bis(Schiff base)-p-menthane derivative, whose pre-emergence herbicidal activity against ryegrass was determined by using the Petri dish seed germination method. The 1,8-bis(Schiff base)-p-menthane derivatives, obtained with this method in high yield and mild reaction conditions, have a good inhibitory effect on the growth of annual ryegrass, and low toxicity.
