15 October 1993Liquid-crystalline paramagnetic Cu(II) complexes of enaminoketone ligands
Studies of complexes: [R-C6H4-CO(CH)2N-Alk]2Cu, (I), [Alk-CO(CH)2N-C6H4-R]2Cu, (II), and [R1-C6H4-CO(CH)2N-C6H4-R2]2Cu, (III), for various terminal substituents R, R1, R2, are presented. For alkyl substituents R, complexes are low- melting and low-clearing nematics [group (I)] and smectics A [group (II)]. Mesophases are monotropic for pure compounds, enantiotropic for mixtures. Elongation of molecular core by introduction trans-cyclohexyl rings into R substituents leads to enantiotropic paramagnetic mesogens. Complexes of the group (III) are high-melting and high-clearing mesogens which usually undergo decomposition in the isotropic phase.
