为了观察由半导体单壁碳纳米管（s-SWCNT）上的激子形成移动的载流子的明确实例，所述半导体单壁碳纳米管（s-SWCNT）被具有高介电常数的介质包围，通过使用含有脂肪族核的聚（酰胺基胺）树枝状聚合物的物理改性来制造水分散性s-SWCNT纳米复合材料。使用这些s-SWCNT/树枝状聚合物纳米复合物作为光敏剂在可见光照射下从水中放出H-2，证明了从s-SWCNT到助催化剂的光诱导电子转移。
To observe a clear-cut example of the formation of mobile carriers from excitons on semiconducting single-walled carbon nanotubes (s-SWCNTs) surrounded by a medium with a high dielectric constant, water-dispersible s-SWCNT nanocomposites were fabricated by physical modifications using poly(amidoamine) dendrimers that contain an aliphatic core. The evolution of H-2 from water using these s-SWCNT/dendrimer nanocomposites as photosensitizers under irradiation with visible light demonstrated a photo-induced electron transfer from the s-SWCNTs to the co-catalysts.
