Formation of Hollow Helicoids in Mesoporous Silica: Supramolecular Origami
Source abstract
Abstract
Siliceous hollow helicoids (Archimedian screw shapes) with spiraling mesoscale channels are the result of a new way of controlling the growth and form of hexagonal mesoporous silica. These novel helicoids (see Figure) are produced when a patch of the hexagonal silicate liquid-crystal film contracts on hydrolytic polycondensation, triggering “roll-up”. A supramolecular Origami theoretical model is invoked to rationalize hollow helicoid formation.
