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 (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 CH2Cl2 (K-sv similar to 10(6) mol(-1) L) or film.
