Porous polymers have immense potential in catalysis, energy conversion and storage, separation sciences and life sciences due to their high surface area and high diffusion flux. Developing porous polymers with micro and mesoscale porosity with long-range order is challenging and involves multistep templated approaches. Here we demonstrate a simple surface-oxygen induced electropolymerization route to directly obtain self-assembled porous polymers of polyparaphenylene (PPP) and PPP based copolymers in ionic liquids. By combining experimental and theoretical studies, we show that surface oxygen on Cu changes the orientation and assembly of benzene which then results in a change in electropolymerization mechanism leading to a selfassembled porous structure with porosity between 2 and 5 μm. Furthermore, with controlled experimental parameters, bicontinuous conducting polymers with porosity of >10 μm are obtained. The porous conducting polymers show absorption of light in the visible range which was also used as an efficient electrode for investigation of the photo/electrochemical oxygen evolution reaction.

用于电催化的介孔导电聚合物的表面氧诱导电化学自组装

多孔聚合物由于其高表面积和高扩散通量，在催化、能量转换和存储、分离科学和生命科学方面具有巨大的潜力。开发具有长程有序的微孔和中孔多孔聚合物具有挑战性，并且涉及多步模板化方法。在这里，我们展示了一种简单的表面氧诱导电聚合途径，可直接在离子液体中获得聚对亚苯基 (PPP) 和基于 PPP 的共聚物的自组装多孔聚合物。通过结合实验和理论研究，我们表明 Cu 上的表面氧改变了苯的取向和组装，然后导致电聚合机制发生变化，导致自组装多孔结构，孔隙率在 2 到 5 μm 之间。此外，在受控的实验参数下，获得孔隙率 >10 μm 的双连续导电聚合物。多孔导电聚合物显示出对可见光范围内的光的吸收，这也被用作研究光/电化学析氧反应的有效电极。
