Ionic Bent Shape Ternary Facial Amphiphiles



Novel bent shape tenary facial amphiphilic imidazolium ILC which consist of a π-conjugated bent aromatic cores (2,5-dithiophenylethynyl phenyl bent core), two terminal poliphilic alkyl chains and lateral n-alky chain terminated by an imidazolium bromide unit were synthesized by using Kumada and Sonogashira coupling reactions as key steps and both their thermotropic and lyotropic mesophase behaviors were studied by POM, DSC and XRD. Columnar phases were found in these compounds, a hexagonal cylinder model with core shell structure is supposed for the columnar phase formed by compound I/8. Our study may provide a new strategy for designing new LC functional material.
