Mesomorphic properties of bis(5-alkoxy-2-aminotroponato)coppers and their N,N-dimethyl derivatives
Unsymmetrical bis(5-alkoxy-2-aminotroponato) coppers showed tilted smectic C and G/J phases due to the alignment of the outboard dipole moment. Furthermore, their N, N-dimethyl derivatives had nematic and smectic A phases with low transition temperatures due to the reduction of the lateral overlapping and the steric repulsion of the methyl groups.
