• phase was observed. The relationship between the molecular structure and mesomorphic properties of these new LCs with hydrophilic chains is discussed. Keywords: contact cell preparation; hydrophilic chain; lamellar phase; lyotropic liquid crystal; thermotropic liquid crystal; Introduction All

• using the contact-cell preparation technique. For our studies, water and/or diethylene glycol were used as the solvent. However, after careful testing of all the materials only TL4 clearly shows the lyotropic phase in contact with diethylene glycol starting at the temperature of 109 °C, which is lower
