Anthrylene- and ferrocenoyl-assisted composite fabrication was achieved between visible-light absorbing anthrylene- and ferrocenoyl-substituted acetylenic dyes and single-wall carbon nanotubes (SWCNTs). The composite formation was confirmed via UV-Vis, Raman, mass, and XPS spectra analyses. In the UV-Vis absorption spectrum, the resulting dye-SWCNT composites showed bathochromic shifts ascribable to the π-π interaction. One-pot fabrication of the composite was also accomplished via Cu-catalyzed dimerization of anthrylene- and ferrocenoyl-substituted terminal ethyne and the subsequent adsorption of the resulting butadiyne dye to SWCNT. We confirmed that the dye-SWCNT composite dispersed in water by using amphiphilic poly(amidoamine)dendrimer could transfer an electron from 1-benzyl-1,4-dihydronicotinamide (BNAH) to methyl viologen dichloride (MV2+) upon irradiation with visible light (>422 nm).
在可见光吸收蒽基和二茂铁基乙炔染料与单壁碳纳米管(SWCNT)之间实现了蒽基和二茂铁基乙炔辅助复合物制造。通过紫外-可见光、拉曼、质谱和XPS光谱分析证实了复合物的形成。在紫外-可见光吸收光谱中,所得染料-SWCNT复合物显示出可归因于π-π相互作用的色移。通过铜催化的蒽基和二茂铁基乙炔二聚反应以及随后所得丁二炔染料对SWCNT的吸附,也实现了复合物的单锅制造。我们证实,使用两性聚(酰胺胺)树状聚合物分散在水中的染料-SWCNT复合物可以在可见光(>422 nm)照射下将电子从1-苄基-1,4-二氢烟酰胺(BNAH)转移到甲基紫精二氯化物(MV2+)。
