Provided is a thermal responsive molecule favorable as a thermal responsive low-molecular hydrogelling agent or the like that gels in response to heat. The thermal responsive molecule is characterized in that an amphiphilic side chain obtained by bonding a hydrophilic side chain such as triethylene glycol and a hydrophobic group such as an octyl group is introduced into a C

-symmetric disc-shaped molecular skeleton such as 1,3,5-benzenetriyltriurea. For example, the thermal responsive molecule is 1,1′,1″-(benzene-1,3,5-triyl)tris3-(2,5,8,11-tetraoxaheptadecan-17-yl)urea} or the like.
提供的是一种热响应分子,可作为热响应低分子水凝胶剂等,对热作出凝胶反应。该热响应分子的特征在于,在诸如1,3,5-苯三甲酰脲等C3对称的扁平分子骨架中引入了一种两亲侧链,该侧链是通过将亲水性侧链(如三乙二醇)和亲疏性基团(如辛基)结合而成的。例如,该热响应分子是1,1',1''-(苯-1,3,5-三基)三3-(2,5,8,11-四氧庚十七基)脲}或类似物。
