Title: Spontaneous self-assembly of partially fluorinated bolaamphiphiles into ordered layered structures
Abstract: We developed a simple method for preparation of well-defined films of T- and anchor-shaped bolaamphiphiles. The compounds were judiciously to investigate the influence of the general molecular structure the self-assembly properties. Precisely calculated (on the basis of pi(A) isotherms) volumes of chloroform solutions of the of known concentrations were spread (drop-casted) directly the surface of water or silicon wafer. During the solvent regular thin films were spontaneously formed. With use of drop-casting (DC) method, films of thickness of up to three layers could be obtained. X- ray reflectivity (XRR) gave insight into arrangement of the molecules within the Different models of molecular organisation in the films were with the experimental results. Advanced fitting procedures for precise determination of the structure of the films. of films of different compounds obtained using different (Langmuir-Blodgett, DC) allowed for a deeper insight into the of self-assembly, providing guidelines for designing functional spontaneously forming thin, regular films. The proposed DC is a novel alternative to broadly used self-assembled (SAMs). Unlike SAMs, our method does not require specific interactions and allows formation of films thicker than a monolayer.
