Polyelectrolyte complexes formed from conjugated polymers: array-based sensing of organic acids
Abstract One fluorescent, positively charged poly(para-phenyleneethynylene) (PAE?1) forms electrostatic complexes with five negatively charged pyridine- or benzothiadiazole-containing poly(para-aryleneethynylene)s (PAE?2?PAE?6). The PAE?2?PAE?6 are less fluorescent in water and act as quenchers for...

| Summary: | Abstract One fluorescent, positively charged poly(para-phenyleneethynylene) (PAE?1) forms electrostatic complexes with five negatively charged pyridine- or benzothiadiazole-containing poly(para-aryleneethynylene)s (PAE?2?PAE?6). The PAE?2?PAE?6 are less fluorescent in water and act as quenchers for PAE?1 in their electrostatic complexes C?1?C?5; the PAE-complexes (2??m) were exposed to thirteen different carboxylic acids (50?mm) in buffered aqueous solution. The fluorescence responses of the small library of electrostatic PAE?complexes towards the acids was analyzed; discrimination of all of the thirteen acids was achieved. The investigated acids include acetic, butyric, tartaric, maleic, lactic, sorbic, oxalic, aspartic, and citric acids. A random, simple, ad-hoc library of electrostatic polymer complexes, C?1?C?5, therefore discerns the thirteen carboxylic acids in water. |
