Ma. Guillevic et al., The synthesis and mesomorphism of mesogenic imines with fluorocarbon chains and their complexes with rhenium(I): New materials with cubic phases, MOLEC CRYST, 362, 2001, pp. 147-170
In this paper, we describe the synthesis of some imine ligands bearing fluo
rinated chains and their metal complexes with Re(I). Whereas related ligand
s with hydrocarbon chains show nematic and S-C phases, the new ligands show
S-A and S-C phases. However, when both terminal chains are fully fluorinat
ed, then the ligand additionally show a cubic phase. Metal complexes of the
fluorinated ligands show a S-A phase before decomposing.
The mesomorphism of both the complexes and the ligands is discussed and the
formation of cubic phases in these imines is explored in relation to other
materials showing a cubic phase.
