摘　　要：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 reaction conditions,the resulting porous polymer shows exceptionally nanotubular morphology,which further allows for a template-free synthesis of porous carbon nanotubes via thermal treatment at high temperature.The obtained nitrogen-doped carbon nanotubes feature with an improved porosity and high surface area.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）.
