Chiral gels using a repeating helicoidal molecular rotation of optically anisotropic soft matter such as nematic liquid crystals and the reactive mesogenic elastomer self-organize a periodic dielectric tensor. The helical structure results in modulation of electromagnetic light propagation when the periodicity has matched the wavelength of the light and can allow further wavelength tunable properties against addressing various external stimuli including temperature, light, electric field, and mechanical deformation. Especially, mechanochromic response behaviors of chiral gels which are from elastomer are particularly interesting for photonics applications. In this study, we studied the simple and easy fabrication procedure of chiral gels with elastomers via two-stage Thiol-Michael addition reaction and their optical characteristics by mechanical deformation. Detailed optical behaviors of fabricated chiral gels will be discussed either with high optical quality and wide tunability. |
