;Trinh, Thi Minh Nguyet ;Nguyen, Thanh Tung ;Kopp, Cyril ;Pieper, Pauline ;Russo, Virginie ;Heinrich, Benoît ;Donnio, Bertrand ;Nguyen, Thi Le AnhThe olefin cross-metathesis reaction using the second-generation Grubbs catalyst was employed to prepare non-symmetrical thermotropic liquid crystals from various mesomorphic or nonmesomorphic type I and type II olefinic constructs, including linear, chiral, dendritic and ferrocenyl olefins. Smectic C, smectic A and nematic phases, as well as chiral smectic A and chiral nematic phases were observed in agreement with the structure and nature of the mesogens. The olefin cross-metathesis proved to be a valuable chemical reaction in designing dimeric and Janus-like thermotropic liquid crystals built from two different molecular entities.
