Reversible Scrolling of Two-Dimensional Sheets from the Self-Assembly of Laterally Grafted Amphiphilic Rods

Deep-water scrolls: It is demonstrated that amphiphilic rods containing lateral flexible chains self-assemble into two-dimensional sheets in aqueous solution (see picture). Remarkably, the sheets roll up reversibly into tubular scrolls upon heating, as confirmed by cryo-transmission electron microsc...

Summary:Deep-water scrolls: It is demonstrated that amphiphilic rods containing lateral flexible chains self-assemble into two-dimensional sheets in aqueous solution (see picture). Remarkably, the sheets roll up reversibly into tubular scrolls upon heating, as confirmed by cryo-transmission electron microscopy and fluorescence microscopy.
