In this paper, we describe the synthesis of some imine ligands bearing fluorinated chains and their metal complexes with Re(I). Whereas related ligands 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 fluorinated, 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.

The synthesis of perfluoroalkyl and perfluoroalkylether substituted benzils
C8F17C6H4CHO, C8F17C6H4CO2H, C8F17C6H4COCOC6H5, and C8F17OCF2CF2C6H4COCOC6H5 proceeded readily. No C8F17OCF2C6H4COCOC6H5 was produced from the reaction of C8F17OCF2I with 4-iodobenzil in the presence of copper bronze. Low yields of bridged bisbenzils were obtained from the coupling reactions of ICF2CF2O(CF2)5OCF2CF2I and I(CF2CF2O)5CF2CF2I with 4-iodobenzil. Based on by-products formed, the operative
