A new 6-benzylaminopurine-functionalized disubstituted polyacetylene (P2) with strong green fluorescence is successfully synthesized by utilizing a postfunctional method. P2 is soluble in common organic solvents, and its strong green fluorescence 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), making P2 a practical, sensitive, and selective copper and cobalt probe.
