Outline of Final Research Achievements

Various types of joint-rod gels were synthesized using a click reaction of multi-functional thiol compounds as joint molecules and diacrylate compounds as rod molecules. SMILS analysis of the resulting gels cleared that homogeneous network structures in the gels. Mechanical properties of the gels were investigated by compression test. The results showed the relationship between the network structure and the mechanical properties of the gels. The gels containing low molecular functional compounds or in the functional solvents were synthesized, and showed the properties derived from the functional materials in the gels.
