Wayne Hayes, University of Reading, UK, and colleagues, synthesized and characterized a focused library of potential low molecular weight hydrogelators for novel inexpensive and easy to use water purification platforms. The pH switchable, color changing gels can sequester large, but varying quantities of the aromatic cationic dye from aqueous solution.
