Enantioselective Graphene-Based Chemical Sensors Prepared via Chiral Functionalization |
| 초록 |
Discrimination of enantiomeric chemical molecules is one of the most important issues in chemical and biological fields due to the chirality-induced different properties of enantiomers. Here, we report the development of graphene transistor-type chemical sensors with pyrene-based chiral functionalization molecule. Chiral functionalization molecule itself showed different optical responsivity for addition of different β-citronellol enantiomers. Graphene transistor sensor was functionalized using simple solution deposition of chiral functionalization molecule via the strong π-π interaction between graphene and pyrene moiety of chiral functionalization molecule. Developed enantioselective chemical sensor successfully discriminated enantiomer of β-citronellol, in vapor phase sensing. Our results represent a significant step towards the improvement of chiral electronics field. |
