A novel gelator including a sugar derivative; a gelator including a compound of Formula (1) or Formula (2): wherein Ris a linear or branched alkyl group having a carbon atom number of 9 to 20, a cyclic alkyl group having a carbon atom number of 13 to 20, or a linear or branched alkenyl group having a carbon atom number of 9 to 20, Ris a hydrogen atom, a linear or branched alkyl group having a carbon atom number of 1 to 10, or an aryl group optionally having a substituent, and Rand Rare hydroxy groups.

Sugar derivative gelators

There is provided a novel gelator containing a sugar derivative. A gelator including a compound of Formula (1) or Formula (2): wherein each of Rand Ris independently a linear or branched alkyl group having a carbon atom number of 1 to 20, a cyclic Calkyl group, or a linear or branched alkenyl group having a carbon atom number of 2 to 20, n is 0 or an integer of 1 to 4, Ris a hydrogen atom, a linear or branched alkyl group having a carbon atom number of 1 to 10, or an aryl group optionally having a substituent, and Rand Rare each a hydroxy group.

Sugar-derived gelator

The present invention relates to an electrochromic polymer compound composed of a hyperbranched polymer having electrochromic characteristics derived from a quaternary pyridinium salt, a terephthalic acid diester or a biphenyl-4,4'-diester structure, and a varnish, a thin film structure and an electrochromic device that are obtained by the polymer compound. The electrochromic material has high response speed, high coloring efficiency, and excellent repetition stability and can be used for a long time, and has excellent solubility in various solvents.
