以三（4-氯苯基）膦为单体，通过Yamamoto型Ullmann交叉偶联反应，设计并合成了一种新型电活性多孔芳香骨架（JUC-Z4-Cl）。通过简单的氧化还原化学反应，可以得到稳定、还原性、多孔的聚三（对苯基）膦（JUC-Z4）和聚三（对苯基）氧化膦（JUC-Z5），为灰白色粉末。JUC-Z4和JUC-Z5的结构使用魔角旋转核磁共振光谱、傅里叶变换红外光谱等进行了确认。微孔结构表现出高稳定性（JUC-Z4为471°C，JUC-Z5为484°C）和大表面积（JUC-Z4和JUC-Z5分别为793和648 m2 g−1）。JUC-Z4还表现出对干燥空气中温室气体的有效识别能力。
A novel electroactive porous aromatic framework (JUC-Z4-Cl) was designed and synthesized via Yamamoto-type Ullmann cross-coupling reaction with the monomer tris(4-chlorophenyl)phosphine. By simple redox chemical reactions, stable, reductive, porous polytri(p-phenyl)phosphine (JUC-Z4) and polytri(p-phenyl)phosphine oxide (JUC-Z5) could be obtained as off-white powders. The structures of JUC-Z4 and JUC-Z5 were confirmed using magic-angle spinning nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy, etc. The microporous architectures exhibit high stability (471°C for JUC-Z4 and 484°C for JUC-Z5) and large surface area (793 and 648 m2 g−1 for JUC-Z4 and JUC-Z5, respectively). JUC-Z4 also exhibits efficient recognition ability of greenhouse gases from dry air.
