Shape-shifting: A method for reversibly transforming the shape of organic waveguides to form 2D nanosheets, 1D nanotubes, and 0D nanorings has been developed. The nanosheets can be turned into nanotubes and subsequently into nanorings by adding water to the solvent, whereas ultrasonication changes the nanotubes back into nanosheets. Both nanotubes and nanosheets act as waveguides and change the direction of incident laser light in a shape-dependent manner.
