A novel hyperbranched conjugated chemosensor with bipyridyl groups as periphery groups(BPY-HPV)was synthesized.BPY-HPV was highly sensitive to metal ions(Cu²⁺, Ni²⁺)for the strong coordination interaction(K_sv at the order of 10⁷ 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 CH₂C1₂(K_sv~10⁶ mol^-1 L)or film.
