A New Disubstituted Polyacetylene Bearing 6-Benzylaminopurine Moieties: Postfunctional Synthetic Strategy and Sensitive Chemosensor Towards Copper and Cobalt Ions
关键字：chemosensors, conjugated polymers, copper and cobalt detection, polyacetylene
A new 6-benzylaminopurine-functionalized disubstituted polyacetylene (P2) with strong green fl uorescence is successfully synthesized by utilizing the postfunctional method. The polymer is soluble in common organic solvents, and its strong green fl uorescence can be quenched by copper and cobalt ions with a detection limit down to 1.0 × 10-8 (0.64 ppb) and 3.3 × 10-8 mol L-1 (1.94 ppb), respecti...
