Abstract

Electrically tunable color by using mixtures of bent-core and rod-shaped molecules was investigated. Differential scanning calorimetry (DSC) and textural observations showed complete miscibility with 6OO8 for both bent-core compounds. The I-N transition enthalpies linearly decreased from about 3Jg ^-1 to 0.7Jg^-1 from 100% to 0% 6OO8 content. Control measurements involving other rod-shape materials with a SmC, an SmA, or N and SmA phases, only showed complete miscibility and induced smectic phases for the one with SmC phase, indicating the importance of the titled structure. It was observed that the fast switching speed in a wide temperature range with uniform alignment offers immediate applications.
