We previously reported that a copolymer consisting of N-isopropylacrylamide (NIPAM) and benzophenone (BP) units, behaves as a photosensitizer showing temperature-controlled oxygenation activity in water (J. Am. Chem. Soc. 2006, 128, 8751). This polymer shows a heat-induced oxygenation enhancement at low temperature region (5–20°C), while showing a heat-induced oxygenation suppression at high temperature...
Effects of poly-N-isopropylacrylamide (polyNIPAM) on the fluorescence properties of core/shell type CdS/Cd(OH) 2 nanoparticles (NPs) have been studied in water. The NPs show strong fluorescence at low temperature, but the intensity decreases at >32°C, allowing an on–off fluorescence switching by temperature. The heat-induced fluorescence quenching is due to the phase transition of polyNIPAM...
