Intermolecular approach to metal ion indicators based on polymer phase transitions coupled to fluorescence resonance energy transferElectronic supplementary information (ESI) available: 1H and 13C NMR spectra for all documented compounds; ratiometric response of the polymer indicator to various metals; fluorescence studies of the indicator with increasing temperature. See DOI: 10.1039/c2an35771b
An approach to ratiometric fluorescence detection of quenching metal ions was devised by copolymerizing N -isopropylacrylamide with small percentages of bipyridine and amine monomers. The copolymer was divided into two portions. The amine group on one portion was functionalized with AlexaFluor555 (d...
