| 英文摘要 | A new poly(p-phenylene ethynylene) derivative with pendant 2,2'-bipyridyl groups and glycol units (ppe-bipy) has been prepared, and its metal ion sensing properties were investigated. the polymer of ppe-bipy exhibited high selectivity for hg2+ as compared with li+, na+, k+, ba2+, ca2+, mg2+,al3+, mn2+, ag+, zn2+, ph2+, ni2+, cd2+, cu2+, co,(2+) and fe3+ in thf/etoh (1:1, v/v) solution. the fluorescence of ppe-bipy was efficiently quenched by hg2+ ions, and the detection limit was found to be 8.0 nm in a thf/etoh (1:1, v/v) solvent system. ppe-bipy also showed a selective chromogenic behavior toward hg2+ ions by changing the color of the solution from slight yellow to colorless, which can be detected with the naked eye.
