芳烃-全氟芳烃设计调控多孔有机光催化剂局部静电，邻位桥接提升Ni/光氧化还原C–N偶联产率
Arene-Perfluoroarene-Enabled Electrostatic Modulation in Organic Porous Photocatalysts for Ni/Photoredox C–N Coupling
AI 导读
研究者以芳烃-全氟芳烃（AP）结构设计构建4CzIPN衍生的多孔光氧化还原聚合物，用邻、间、对位联苯桥连接咔唑与全氟咔唑单元。KPFM测得o-CBCP、m-CBCP、p-CBCP和无AP对照P(4Cz)的光致接触电势差（CPD）位移分别为27.1、18.3、5.0和4.3 mV，o-CBCP在425 nm蓝光LED下的表面光电压响应更强、拟合中频电阻最低。
推荐理由
通过邻/间/对位联苯桥接调控多孔有机光催化剂的局部光致静电，并用KPFM把连接方式与催化产率对应起来。
创新点
把芳烃-全氟芳烃连接几何（邻/间/对位）作为调节无序多孔聚合物光响应局部静电的分子手段，并建立其与Ni/光氧化还原C–N偶联活性的对应关系。
