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 (Ksv 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 (Ksv ~ 106 mol-1 L) or film.
