摘要：

Seeing red: Highly sensitive and selective chemical sensing systems were developed for the naked-eye detection of toxic ions by the direct and indirect postgrafting of hydrophilic and hydrophobic chromophores into spherically nanosized cavities of cubic Fm3m monoliths (HOM-C10). This leads to reliable control over the visual detection of toxic metals such as PbII, CdII, SbIII, and HgII ions at a low concentrations (≈10-9 M). DZ = diphenylthiocarbazone.
