摘要：
A simple epoxy based polymer 1 bearing a triphenylamine unit is shown to be an on-off type fluorescent sensor for Hg2+ ions in THF-water (4 : 1, v/v; 10 mM HEPES, pH similar to 7.0) with high sensitivity and selectivity. In the sensing process, other metal ions such as Cu2+, Zn2+, Co2+, Ni2+, Cd2+, Pb2+, Mg2+, Ca2+, Sr2+ and Ag+ did not interfere.
