合成了自缩合单体4-(4‘-溴苯基)-4“-正丁基二苯胺(1)，并在钯催化下芳胺化合成了聚对丁基三苯胺(PBTPA)。通过添加芳基溴或芳胺衍生物作为终止剂，可以在PBTPA的两端分别进行官能化，从而制备了两嵌段共聚物PBTPA-嵌段-PEO。通过(1)H-核磁共振、(13)C-核磁共振和DSC对聚合物进行了表征，证实PEO链段被成功引入到PBTPA的末端。用原子力显微镜对PBTPA-嵌段-PEO薄膜的表面形貌进行了观察，结果表明，在不同浓度的1，1，2，2-四氯乙烷溶液中旋转浇铸制备的PBTPA-嵌段-PEO薄膜形成了微相分离结构或带有PEO球状结构的杯状结构。(C)2008爱思唯尔有限公司。保留所有权利。
A self-condensing monomer 4-(4'-bromophenyl)-4"-n-butyldiphenylamine (1) was synthesized, and successfully converted to poly(4-n-butyltriphenylamine) (PBTPA) by arylamination using palladium catalyst. PBTPAs can be functionalized at both terminals separately by adding an aryl bromide or arylamine derivatives as a terminator, which enabled us to prepare the diblock copolymer PBTPA-block-PEO. Polymer characterization was performed by (1)H NMR, (13)C NMR, and DSC, which confirmed that the PEO segment was successfully introduced at the terminal of PBTPA. The surface morphology in a thin film of PBTPA-block-PEO was examined by AFM, revealing that a micro phase-separated structure or cup-shaped structure with PEO sphere domains formed when the film was spin-cast from 1,1,2,2-tetrachloroethane solutions of different concentrations.
