Supramolecular approaches to visual detection, storage, conversion and use of NO X gases are described that deploy calixarenes and their derivatives, such as hemicarcerands and synthetic nanotubes. Polymer-supported calixarene materials for NO X are

Calix[4]arenes and nanotubes based on them convert NO2/N2O4 gases into nonvolatile NO+ species and encapsulate them. In a one-electron reduction scheme with hydroquinone, the complexed NO+ transforms into NO gas. While NO is released, calixarenes are
