Colorimetric Photothermal Sensing over Wide-Range of Temperatures Using Multicolor Block Copolymer-MoS2 Nanocomposites |
| 초록 |
We developed a nanosize photothermal agent which can operate a self-detection of temperature ranging from 25 to 50 °C through colorimetric responses. In order to achieve photothermal heating and colorimetric sensing over a wide range of temperatures, MoS2 was functionalized with three different BCPs: each BCP is composed of a temperature-responsive block and a fluorescent block. Each temperature responsive block had a different lower critical solution temperature (LCST) to monitor different but complementary temperature ranges. The fluorescent blocks of the three BCPs emitted red, green, or blue light to provide a colorimetric response to temperature changes. The fluorescent intensities of the three BCPs on MoS2 were independently switched on and off with changes in temperature, producing a colorimetric behavior from white to yellow to red and then to green in the range of 25−50 °C with excellent reversibility and stability. |
