MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641050395 A) filed by Manipal Academy Of Higher Education; and Centre For Nano And Soft Sciences, Manipal, Karnataka, on April 20, for 'a method and composition for synthesizing cholesterol-based liquid crystal dimers exhibiting tgbare phase.'
Inventor(s) include Pooja Mohandas; Reshma C; Maddasani Srinivasulu; and Channabasaveshwar V. Yelamaggad.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The current invention relates to a synthetic method for producing cholesterol-derived liquid crystal dimers that display a re-entrant TGBA phase. The synthesized dimers exhibit complex mesomorphic properties, undergoing phase transitions including BPIII/II/I, N*, TGBA, SmA, TGBC*, phase and the recently identified TGBAre phase. These materials possess adjustable optical characteristics and react to external factors like temperature and electric fields. The innovation facilitates the creation of advanced photonic devices such as liquid crystal displays (LCDs), optical filters and nonlinear optical devices, which necessitate dynamic light modulation. The method includes synthesizing cholesterol based acid and alkoxyhydroxybiphenyl derivatives using dehydrating agent and catalyst to produce liquid crystal dimers that display the TGBAre phase, improving the versatility, stability, and adaptability of liquid crystal materials for sophisticated uses in optoelectronics and photonics."
