Synthesis of Fluorinated Bent-Core Mesogens (BCMs) Containing the 1,2,4-Oxadiazole Ring

New fluorinated bent‐core mesogens containing the 1,2,4‐oxadiazole or 1,2,4‐triazole nucleus have been synthesized taking advantage of the ANRORC (Addition of Nucleophile, Ring‐Opening, Ring‐Closure) reactivity of 5‐perfluoroalkyl‐1,2,4‐oxadiazoles. Physical state changes of the obtained compounds w...

Zusammenfassung:New fluorinated bent‐core mesogens containing the 1,2,4‐oxadiazole or 1,2,4‐triazole nucleus have been synthesized taking advantage of the ANRORC (Addition of Nucleophile, Ring‐Opening, Ring‐Closure) reactivity of 5‐perfluoroalkyl‐1,2,4‐oxadiazoles. Physical state changes of the obtained compounds were characterized through DSC, POM, and SAXS. Besides the formation of a smectic mesophase, a novel behavior as organic molecular glass was evidenced for some 1,2,4‐oxadiazole derivatives.
