The Synthesis and Mesomorphism of Mesogenic Imines with Fluorocarbon Chains and their Complexes with Rhenium(I): New Materials with Cubic Phases
摘要:
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.
