Hybridizations of redox‐active polyoxometalates (POMs) with single‐walled carbon nanotubes (SWNTs) have been widely investigated for their diverse applications. For the purpose of constructing high‐quality electronic devices, controlling charge transfer within POM/SWNT hybrids is an inevitable issue. As determined by means of fluorescence spectroscopy, electron transfer between SWNTs and a common POM dopant, phosphomolybdic acid (PMo₁₂), can be tuned simply by an alteration of nanotube surfactant type from anionic to nonionic. The mechanism is attributed to the influence of surfactant type on the stabilization of the electron donor–acceptor hybrid and effect of surfactant–nanotube interactions. These results will be important to control charge‐transport behavior in nanohybrids consisting of carbon nanotubes.

多金属氧酸盐和单壁碳纳米管之间表面活性剂的电荷转移：荧光光谱研究

氧化还原活性多金属氧酸盐（POMs）与单壁碳纳米管（SWNTs）的杂交已被广泛研究用于其各种应用。为了构造高质量的电子设备，控制POM / SWNT混合体内的电荷转移是不可避免的问题。如通过荧光光谱法所确定的，可以简单地通过将纳米管表面活性剂类型从阴离子型改变为非离子型来调节SWNT与常见的POM掺杂剂磷钼酸（PMo ₁₂）之间的电子转移。该机制归因于表面活性剂类型对电子给体-受体杂化体的稳定性的影响，以及表面活性剂-纳米管相互作用的影响。这些结果对于控制由碳纳米管组成的纳米杂化物中的电荷传输行为至关重要。
