Mn. Abser et al., ALKYL-AROYLHYDRAZINATO AND ALKOXY-AROYLHYDRAZINATO METAL-COMPLEXES - UNUSUAL X-RAY-DIFFRACTION WITHIN THE SMECTIC-C PHASE, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 260, 1995, pp. 333-337
Two homologous series of novel nickel containing liquid crystalline co
mplexes have been synthesised (1-3). The effect of changing chain leng
th and chain type on phase behaviour is reported here. Optical microsc
opy, DSC and x-ray scattering is used to identify the phase structures
. X-ray scattering from the smectic C phase shows unusual diffraction
patterns with the intermolecular scattering larger than would be expec
ted.
