Abstract
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 C3-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)tris{3-(2,5,8,11-tetraoxaheptadecan-17-yl)urea} or the like.
Claims4
