Abstract A shape-persistent dendritic molecule, tris (4-(2, 7-dibromo-9-phenyl-9-fluoren-9-yl) phenyl) amine (TF-6Br), has been readily synthesized in high yield through a concise Friedel-Crafts reaction from triphenylamine and 2, 7-dibromo (9-phenyl-fluoren-9-ol). It was further employed as the key building block to achieve the synthesis of conjugated porous polymer via Sonogashira coupling with 1, 4-diethynylbenzene. Under experimental ...
