Spin fluorescence silencing enables an efficient thermally driven self-reporting polymer release systemElectronic supplementary information (ESI) available: Comprehensive experimental and analytical information. See DOI: 10.1039/c7py01437f

We pioneer a self-reporting profluorescent release system driven by the thermo-reversible dynamic covalent ligation of chromophores to a lateral polymer chain, whose fluorescence is silenced by unpaired spins of nitroxide moieties prior to release. The introduced technology platform holds significant potential for imaging substrate release events. A self-reporting profluorescent release system driven by the thermo-reversible dynamic covalent ligation of chromophores to polymer chain, whose fluorescence is silenced by unpaired spins of nitroxides prior to release is introduced.
