Accordion-like swelling of layered perovskite crystals via massive permeation of aqueous solutions into 2D oxide galleries

Chem Commun (Camb). 2015 Dec 14;51(96):17068-71. doi: 10.1039/c5cc05408g.


Platelet crystals of a layered perovskite showed massive accordion-like swelling in a tetrabutylammonium hydroxide solution. The permeation of the solution induced the huge expansion of the interlayer spacing as well as the crystal thickness up to 50-fold, leading to a very high water content of >90 wt%.
