Abstract

Ultrasound triggers the formation of a peptide-based supramolecular gel that is readily doped with CdSe/ZnS quantum dots affording highly luminescent gels. Xerogels are stable for months and possess inherent porosity as probed by hyperpolarized 129Xe NMR affording new light-emitting materials for chemical sensing.
