Tubular Conjugated Polymer for Chemosensory Applications

In this paper, we present the concept of a soluble tubular
conjugated polymer (TCP). We report on a fluorescent 5,5′-Bicalixarene-based
polymer where the calixarene units are seamlessly incorporated in
the conjugated polymeric chain that can respond to a small molecule
complexation inside the hydrophobic cavity. In particular, our system
demonstrated a reversible rapid fluorescence quenching
upon interaction of gaseous nitric oxide with the calixarene moiety.
