A novel chemosensor-bipyridyl end capped hyperbranched conjugated polymer
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(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.
