摘　　要：A novel hyperbranched conjugated chemosensor with bipyridyl groups as periphery groups（BPY-HPV） was synthesized.BPY-HPV was highly sensitive to metal ions（Cu^（2＋）,Ni^（2＋）） for the strong coordination interaction（K_（sv） at the order of 10~7 mol^（-1） L） monitored by fluorescence spectroscopy.Moreover,by hydrogen bonds and charge transfer interaction,BPY-HPV shows strong interaction with 1,1,2,2-tetrachloroethane whatever in CH_2Cl_2（K_（sv）～10~6 mol^（-1） L） or film.A novel hyperbranched conjugated chemosensor with bipyridyl groups as periphery groups（BPY-HPV） was synthesized.BPY-HPV was highly sensitive to metal ions（Cu^（2＋）,Ni^（2＋）） for the strong coordination interaction（K_（sv） at the order of 10~7 mol^（-1） L） monitored by fluorescence spectroscopy.Moreover,by hydrogen bonds and charge transfer interaction,BPY-HPV shows strong interaction with 1,1,2,2-tetrachloroethane whatever in CH_2Cl_2（K_（sv）～10~6 mol^（-1） L） or film.
