摘要：

A novel conjugated polymer containing 2,2'-bipyridyl moiety synthesized through the Wittig reaction not only shows ion-dependent response for transition metal ions with high sensitivity, but also exhibits selective response to Mg2+, which selectively analyzed from the mixture of alkali and alkali earth metal ions.
