摘要: A pyridine-containing poly(aryleneethynylene) (PAE) is investigated, showing surprisingly versatile changes of its photophysical properties in response to external stimuli. Because agglomeration-induced planarization the backbone, this PAE exhibits a significant red-shift absorption and emission, when moving from good poor solvents. The basic lone pair on pyridine unit makes pH-sensitive imparts metallochromic properties, useful for potential detection wide range metal cations, resulting color responses that quenching red-shifted emission.
