采用湿化学方法合成共价键结合的酞菁-(北)给受体结构(PcCu-4SBPTCD)及其原位修饰多壁碳纳米管(MWCNTs)的复合材料,并研究复合材料内部的电荷传输性能.结果表明,酞菁-(北)给受体结构中,酞菁和(北)之间有明显的电荷传输,即合成的酞菁-(北)给受体结构能有效提高电子空穴的分离效率.在该给受体结构中引入多壁碳纳米管能更进一步地提高电子空穴的分离效率.将碳纳米管-酞菁-(北)(MWCNTs-PcCu-4SBPTCD)用于组装有机太阳能电池(OSCs),有望大大提高电池的光电转换效率.

A novel electron donor-acceptor composite(PcCu-4SBPTCD)was synthesized through a wet-chemical method. Muhi-walled carbon nanotubes(MWCNTs),which were introduced into the reaction system of PcCu4SBPTCD,were in-situ modified with the electron donor-acceptor composite.The fluorescence sloectrum of PcCu4SBTCD shows obvious fluorescent quenching,which indicates that this novel electron donor-acceptor composite can improve the separating of electron-hole pairs.The introduction of MWCNTs can improve the separating of electron-hole pairs more efficiently.The MWCNTs-PcCu-4SBPTCD composites will be prospectively used in organic solar cells for increasing the power conversion efficiency.
