Abstract
A new transduction mechanism based on the aggregation of conjugated sensory polymers induced by K+ ions is reported; this new system displays enhanced sensitivity because of energy migration processes and has a high selectivity for K+ over Na+ ions. The poly(p-phenylene ethynylene)s were synthesized by the Sonogashira-Hagihara coupling reaction. [on SciFinder(R)]
