摘要

Three polar poly(para-phen-ylene ethynylene)s(PPE)were synthesized by utilizing the Heck-Sonoga-shira protocol.Two of the PPEs carry p-glucopyranose substituents.Depending upon the linker used between the glycol units and the backbone,the fluorescence of these PPEs can be quenched by Hg~(2+)and Pb~(2+)to a varying degree.Monomeric model compounds that are substituted with only one glucose unit are not efficiently quenched.The presence of many glucose substituents in one PPE assembly led to a large increase in the binding constant to Hg~(2+)and quenching of the fluorescence was amplified.
