Polymer length dependent FRET behavior on temperature-responsive block copolymer grafted MoS2 nanosheets for a light-induced themographic sensor |
초록 |
Grafted polymer chain length and density on a solid surface are of great importance in controlling their conformational behavior. Herein, we investigate that the characteristics of thermally responsive block copolymer integrated molybdenum disulfide composites (BCP-MoS2) in response to temperature profiles depending on chain length and density. Upon near-infrared light exposure, photothermal energy from MoS2 increased local temperature and induced thermally activated conformational transitions of the BCP on MoS2. These leads to fluorescent signal changes caused by distance-dependent Förster resonance energy transfer (FRET) between the BCP and MoS2. Thus, BCP-MoS2 enable simultaneous PT heating and self-thermal imaging in local environment and these FRET activation are highly rely on the polymer length and chain density. |
