제목 | Novel Naked-Eye Colorimetric Sensing and Chromogenic Imaging of Poly(ortho-phenylazonaphthol) Derivatives |
초록 | The chromogenic derivatives sensitive to many different stimuli can be produced which might attract interest in imaging, data storage, and sensing applications. A new series of copolymers containing ortho-phenylazonaphthol group were synthesized to apply to chromogenic imaging and colorimetric sensing. We will describe the novel color imaging properties in the solid state using protection and deprotection of t-Boc groups in the polymer backbone. The polymers with free hydroxyl groups resulted from deprotection of t-Boc groups exhibited considerable red-shift compared to t-Boc-protected polymers. We performed color-patterning using different colors before ( λmax = 341 nm, yellow ) and after deprotection ( λmax = 523 nm, violet ) of t-Boc from the polymers. Furthermore, we performed colorimetric anion sensing based on the keto-enol tautomerism of free hydroxyl groups in polymer backbone resulting in naked-eye color change. 그림 1.
