“…7. ft-Diketonates Sadashiva et al 42 have made a series of /3-diketonate palladium complexes 34 which, for n = 12, show monotropic nematic phases, when R = alkyl or alkyloxy, and Sa phases, when R = Cl, Br, or CN. This is similar to the behavior of related copper complexes (section III.…”

“…These represent the first examples of paramagnetic nematic liquid crystals. Since then a number of different metal fl-diketonates exhibiting nematic phases have been reported (Muhlberger and Haase 1989;Ohta et al 1991;Sadashiva et al 1991;Thompson et al 1991Thompson et al , 1992a.…”

Several new liquid-crystalline materials have been synthesized and their properties investigated. These belong to a series of fl-diketones containing different terminal substituents. Mesophases of the smectic C, smectic A and nematie types have been observed in these /~-diketones. Using these ligands many copper(II) and palladium(II) complexes have also been synthesized and their mesogenic behaviour characterized. Microscopic observations and differential scanning calorimetric measurements show that these chelates exhibit the nematic phase. The DSC data also indicate that the nematic phase of the ligands and complexes is associated with very low clearing transition enthalpies. All the metaUonematogens reported are enantiotropic in nature.
