The complementary use of steady-state and time-resolved spectroscopy in combination with electrochemistry and microscopy are indicative of mutual interactions between semiconducting SWNTs and a water-soluble strong electron acceptor, i.e., perylenediimide. Significant is the stability and the strong electronic coupling of the perylenediimide/SWNT electron donor-acceptor hybrids. Several spectroscopic and spectroelectrochemical techniques, i.e., Raman, absorption, and fluorescence, confirmed that distinct ground- and excited-state interactions occur and that kinetically and spectroscopically well characterized radical ion pair states form within a few picoseconds.
稳态和时间分辨光谱学与电化学和显微镜相结合的互补使用表明，半导体单壁碳纳米管（SWNTs）与一种水溶性强电子受体，即苝二酰亚胺（perylenediimide）之间存在相互作用。显著的是，苝二酰亚胺/SWNT 给体-受体杂化物的稳定性和强电子偶联。几种光谱和光谱电化学技术，即拉曼、吸收和荧光，证实了明显的基态和激发态相互作用，并且在几皮秒内形成了动力学和光谱特征良好的自由基离子对态。
