D-Isosorbide based reactive chiral dopant for temperature sensor |
| 초록 |
Cholesteric liquid crystals (CLCs) that included chiral dopant have attracted much attention in both scientific studies and applications since the tunability of their cholesteric pitch and the corresponding wavelength selective reflection. The helical pitch of the CLCs and the resultant reflected color from them are directly governed by concentration of a chiral agent and temperature. The pitch variation by temperature gives rise to color shift in the device applications. We are synthesized isosorbide and isomannide based chiral dopants. The new chiral molecules have acryloyloxyalkyl group or alkyl group. Photoresponsive helical twisting power (HTP) change studied with reflection spectroscopy of chiral dopant doped CLC cell under UV irradiation. Also the optical texture of the CLC during visible light irradiation from the UV (365 nm) investigated by polarizing optical microscope with crossed polarizers. |
