The Novel Brush Polymers Bearing Thymine moieties on their Bristle Ends with Self Assembly Structures and Mercury Sensing Characteristics |
| 초록 |
Two new brush polyoxyethylenes bearing thymine moieties at the bristle ends have been synthesized as model polymers in which the chemical loading of the thymine functional group into the polymer is maximized. These differences were found to originate in the differences between their morphological structures. The PECH(SO2)-T film has a multi-bilayer structure without interdigitation, in which the layers stack along the out-of-plane of the film and provide a thymine-rich surface. In contrast, the PECH(S)-T film is amorphous with a relatively low population of thymine moieties at the surface. This study demonstrated that a thymine-rich surface is required for recyclable thymine-based polymers to provide highly improved sensitivity and selectivity as well as full reversibility in the sensing of mercury ions. |
