We describe the functionalization of single-wall carbon nanotubes (SWNTs) with 4-(2-trimethylsilyl)ethynylaniline and the subsequent attachment of a zinc-phthalocyanine (ZnPc) derivative using the reliable Huisgen 1,3-dipolar cycloaddition. The motivation of this study was the preparation of a nanotube-based platform which allows the facile fabrication of more complex functional nanometer-scale structures, such as a SWNT-ZnPc hybrid. The nanotube derivatives described here were fully characterized by a combination of analytical techniques such as Raman, absorption and emission spectroscopy, atomic force and scanning electron microscopy (AFM and SEM), and thermogravimetric analysis (TGA). The SWNT-ZnPc nanoconjugate was also investigated with a series of steady-state and time-resolved spectroscopy experiments, and a photoinduced communication between the two photoactive components (i.e., SWNT and ZnPc) was identified. Such beneficial features lead to monochromatic internal photoconversion efficiencies of 17.3% when the SWNT-ZnPc hybrid material was tested as photoactive material in an ITO photoanode.
我们描述了用4-(2-三甲基硅基)乙炔基苯胺对单壁碳纳米管（SWNTs）进行功能化，以及随后使用可靠的惠斯根1,3-偶极环加成反应连接锌酞菁（ZnPc）衍生物的过程。本研究的目的是制备一个基于纳米管的平台，以便能够轻松制造更复杂的功能性纳米级结构，如SWNT-ZnPc杂化物。这里描述的纳米管衍生物通过拉曼光谱、吸收和发射光谱、原子力显微镜和扫描电子显微镜（AFM和SEM）以及热重分析（TGA）等分析技术的组合进行了全面表征。还通过一系列稳态和时间分辨光谱实验对SWNT-ZnPc纳米共轭物进行了研究，并确定了两种光活性成分（即SWNT和ZnPc）之间的光诱导通信。当SWNT-ZnPc杂化材料作为光活性材料在ITO光阳极中进行测试时，这些有益特性导致单色内部光转换效率达到17.3%。
