Patent number: 8772540Abstract: 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.Type: GrantFiled: November 19, 2010Date of Patent: July 8, 2014Assignee: Kyushu University, National University CorporationInventors: Noboru Koga, Satoru Karasawa, Hiroyuki Hayashi
