A New Disubstituted Polyacetylene Bearing 6-Benzylaminopurine Moieties: Postfunctional Synthetic Strategy and Sensitive Chemosensor Towards Copper and Cobalt Ions
A New Disubstituted Polyacetylene Bearing 6-Benzylaminopurine Moieties: Postfunctional Synthetic Strategy and Sensitive Chemosensor Towards Copper and Cobalt Ions
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),
respectively. Moreover, not much interference is observed
from other metal ions, including Li + , Na + , K + , Fe 3 + , Fe 2 + , Ni 2 + ,
Hg 2 + , Mg 2 + , Al 3 + , Zn 2 + , Mn 2 + , Pb 2 + , Ba 2 + , Ca 2 + , Cd 2 + , Ag + , and
Cr 3 + . Furthermore, P2 can be put into application using test
strips, making P2 a practical, sensitive, and selective copper
and cobalt probe.
