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.
spectral characteristics of fluorinated derivatives of alkylbenzoicacids (FABA) were studied in the temperature range 100–550 K. Experimental values of temperatures, enthalpies and entropies of phase transitions, as well as hydrogen bond energy at different temperatures and in the various physical (phase) states were compared to those for alkyl- and fluoroalkyl-benzoic acids.
