Thermo-responsive

hyperbranched copoly(bis(N, N-ethyl

acryl amide)/(N, N-methylene bisacrylamide)) (HPEAM-MBA) was synthesized by using reversible addition-fragmentation chain-transfer polymerization (RAFT). Interestingly, the zinc ion (Zn2+)

was found to exhibit a crucial influence on the lowest critical solution

temperature (LCST) of the thermo-responsive polymer. The tetraphenylethylene

(TPE) unit was then introduced onto the backbone of the as-prepared

thermo-responsive polymer, which endows a Zn2+-responsive “turn-off”

effect on the fluorescence property. The TPE-bearing polymer shows a highly

specific response over other metal ions and the “turn-off” response can even be

tracked as the concentration of Zn2+ reducing to 2 ×10-5M. The decrement of fluorescence intensity was

linearly dependent with the concentration of Zn2+ in the range of

4-18 μmol/L. The flexible, versatile and feasible approach, as well as the

excellent detection performance, may generate a new type of Zn2+

probes without the tedious synthesis of the moiety

bearing Zn2+ recognition units.
