Abstract

Abstract : 2D assembly of amphiphilic molecules in aqueous solution is a challenging and intriguing topic as it is normally thermodynamically unfavorable. However, through frame‐guided assembly strategy and using DNA origami as the frame, monodispersed and shape‐defined nanosheets are prepared. As leading hydrophobic groups (LHGs) are anchored on the frames, amphiphilic molecules in aqueous solution are guided to assemble in the hydrophobic region. By adjusting the distribution of the LHGs, the size and shape of the assemblies can be controlled precisely.
