Fluorescent and Hierarchically Porous Polymer Monolith with Triphenylene-Based Microporous Network |
| 초록 |
Recently, fluorescent porous polymers have drawn intensive attention due to their potential in sensing application. Fluorophores should be properly installed on the surface of the porous polymer network retaining the fluorescence properties in order to maximize contact with the target substances. In case of the electron-rich fluorophores, adsorption of electron-deficient molecules such as nitroaromatics can be detected by fluorescence quenching. We demonstrate that hierarchically porous polymer monolith containing three-dimensionally continuous mesoporous space can improve the sensing performance by facilitating diffusion of analytes to the fluorescence active site on micropore surface. We discuss construction of such pore structure including triphenylene as the fluorophore by utilizing RAFT polymerization, and their fluorescence quenching behavior in the solid state. |
