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 microscopy and fluorescence microscopy.
