The cyclopalladation reaction of the liquid crystalline species p-dodecyloxy-p'-methylazobenzene (DOMAB) leads to the bimetallic metallo-mesogene [(DOMAB)Pd Cl]2. Both the organic compound and its palladium organometallic complex have been investigated by quasielastic neutron scattering experiments in the nematic and smectic A phases. For DOMAB, the results exhibit a continuous rotation as expected for usual rod-like liquid crystals, while for [(DOMAB)Pd Cl]2 they suggest a model wherein only some aliphatic protons can give a rotational diffusion.

Abstract

The cyclopalladation reaction of the liquid crystalline species p-dodecyloxy-p'-methylazobenzene (DOMAB) leads to the bimetallic metallo-mesogene [(DOMAB)Pd Cl]2. Both the organic compound and its palladium organometallic complex have been investigated by quasielastic neutron scattering experiments in the nematic and smectic A phases. For DOMAB, the results exhibit a continuous rotation as expected for usual rod-like liquid crystals, while for [(DOMAB)Pd Cl]2 they suggest a model wherein only some aliphatic protons can give a rotational diffusion.
