Efficient Colorimetric Sensing Platform based on Responsive Polymer-Quantum Dot Tagged Graphene Oxide |
| 초록 |
Two different pH responsive polymer brushes coated Blue and Orange quantum dots (QDs) were synthesized and grafted on graphene oxide (GO), and their pH responses were quantitatively investigated by photoluminescence (PL) and color change from Blue to orange. GO was functionalized with poly(acrylic acid) (PAA)-pyrene coated blue CdS/ZnS QDs and poly(2-vinylpyridine) (P2VP)-pyrene coated orange CdSe/ZnS QDs by π-π stacking interaction between pyrene and GO. The FRET from QDs to GO was controlled through manipulation of the conformational features of the P2VP and PAA chains that respond to pH changes in solution. The color of solution was gradually changes from blue to orange due to different pKa value of P2VP and PAA. |
