Soluble and high-molecular-weight precursor polythiophenes were synthesized via copolymerization. Post-polymerization reactions installed calixarenes as side chains onto the polymer backbone. The resulting calixarene-containing polythiophenes were utilized to disperse single-walled carbon nanotubes. The stable homogeneous suspensions were easily processed to sensors for selective detection of aromatic isomers.
