New SmAP F Mesogens Designed for Analog Electrooptics Applications

We have previously reported the first realization of an orthogonal ferroelectric bent-core SmAP phase by directed design in mesogens with a single tricarbosilane-terminated alkoxy tail.

Description
Summary:We have previously reported the first realization of an orthogonal ferroelectric bent-core SmAP phase by directed design in mesogens with a single tricarbosilane-terminated alkoxy tail. Given the potentially useful electrooptic properties of this phase, including analog phase-only electrooptic index modulation with optical latching, we have been exploring its "structure space", searching for novel SmAP mesogens. Here, we report two classes of these-the first designed to optimize the dynamic range of the index modulation in parallel-aligned cells by lowering the bend angle of the rigid core, and the second expanding the structure space of the phase by replacing the tricarbosilane-terminated alkyl tail with a polyfluorinated polyethylene glycol oligomer.
