Abstract: A water-soluble nonfluorescent cationic conjugated polyelectrolyte poly(1,1′-((1,4-phenylenebis(oxy))bis(propane-3,1-diyl))bis(pyridin-1-ium)bromide) (PPPy) was specifically synthesized via an economical method of oxidative coupling polymerization in high yields. PPPy selectively recognized nitroexplosive picric acid (PA) by fluorescence “turn-on” in the presence… read more here.
