Here, we report the design and synthesis of a redox-active multifunctional ionic porous organic polymer iPOP-Bpy with exchangeable Br ions, incorporating viologen as a redox-active building block. The material shows not only excellent iodine uptake capacity in the vapor phase (540 wt %) but also in the organic (1009.77 mg g–1) and aqueous phases (3921.47 mg g–1) with very fast adsorption kinetics in all cases. The material also shows its utility in being used as a solid-state NH3 vapor sensor as it shows very fast color switching in the presence of NH3 vapor. Furthermore, the material found application as a p-type complementary electrochromic electrode and was fabricated into a bilayer device. Excellent coloration efficiency, high switching speed, and good color contrast were obtained as investigated using bias-dependent optical and spectroelectrochemical studies, paving the way for fabricating power-efficient solid-state electrochromic devices.

探索氧化还原活性离子多孔有机聚合物在环境修复和电致变色应用中的应用

在这里,我们报告了具有可交换 Br -离子的氧化还原活性多功能离子多孔有机聚合物 iPOP-Bpy 的设计和合成,并将紫精作为氧化还原活性结构单元。该材料不仅在气相 (540 wt%) 中而且在有机相 (1009.77 mg g -1 ) 和水相 (3921.47 mg g -1 ) 中都表现出出色的吸碘能力,在所有情况下都具有非常快的吸附动力学。该材料还显示了它在用作固态 NH 3蒸气传感器方面的实用性,因为它在 NH 3存在的情况下显示出非常快速的颜色转换汽。此外,该材料可用作 p 型互补电致变色电极,并可制成双层器件。使用偏压相关光学和光谱电化学研究获得了优异的着色效率、高切换速度和良好的颜色对比度,为制造节能固态电致变色器件铺平了道路。
