我们开发了一种制备金属纳米颗粒/聚噻吩纳米管复合材料的新方法，即，在作为模板的纳米多孔氧化铝膜中，基于模板的三噻吩连接的低聚乙烯氧基硫醇（1）和膦（2）稳定的金和钯纳米颗粒（1-Au、1-Pd和2-Pd）的电化学聚合得到聚噻吩和金属纳米颗粒的纳米管复合物（1-Au-PT-NT、1-Pd-PT-NT和2-Pd-PT-NT），而没有金属纳米颗粒的聚集。用扫描电镜和透射电镜对纳米管复合材料进行了表征。Pd/聚噻吩纳米管复合材料（2-Pd-PT-NTs）是可回收的高效碳-碳偶联反应催化剂。这种新方法目前正在扩展到其他金属和金属氧化物纳米颗粒/聚噻吩纳米管复合材料，以实现广泛的混合纳米材料与可控的表面化学。
We have developed a new method for the fabrication of metal nanoparticle/polythiophene nanotube composites, i.e., the template-based electrochemical polymerization of terthiophene-linked oligoethyleneoxy-thiol (1) and -phosphine (2)-stabilized gold and palladium nanoparticles (1-Au, 1-Pd, and 2-Pd) in a nanoporous alumina membrane as a template gave the nanotube composites (1-Au-PT-NTs, 1-Pd-PT-NTs, and 2-Pd-PT-NTs) of polythiophene and the metal nanoparticles without aggregation of the metal nanoparticles. The nanotube composites were characterized by scanning electron microscopy and transmission electron microscopy. The Pd/polythiophene nanotube composites (2-Pd-PT-NTs) are recyclable highly effective catalysts for carbon−carbon coupling reactions. This new method is currently being extended to other metal and metal oxide nanoparticles/polythiophene nanotube composites to realize a wide range of hybrid nanomaterials with controllable surface chemistry.
