Graphical Abstract
Nanotube detects isomers: A chemiresistive material based on carbon nanotubes wrapped with a calixarene-substituted polythiophene displays a selective and sensitive response to xylene isomers (see picture), as demonstrated by conductance changes, quartz crystal microbalance, and fluorescence studies. This demonstrates the promise of low-cost, real-time sensors utilizing host–guest chemistry.
