  Synthesis and Photophysical Properties of Electron-Rich Perylenediimide-Fullerene Dyad

  摘要：

  An electron-rich perylenediimide-C-60 dyad has been prepared to explore a new type of donor-acceptor system. Time-resolved absorption measurements in benzonitrile revealed unambiguous evidence for the formation of a charge-separated state consisting of perylene diimide radical cation and C-60 radical anion via photoinduced electron transfer, showing a new class of artificial photosynthetic models in terms of charge separation.

  微波辅助的多壁碳纳米管的共价侧壁官能化。

  摘要：

  1,3-偶极偶氮甲亚胺基团在多壁碳纳米管（MWNT）侧壁上的热环加成已被用于制备包含2-亚甲基硫醇-4-（4-十八烷基氧苯基）（4），N-辛基-2-（ 4-十八烷基氧基苯基）（5）或2-（4-十八烷基氧基苯基）吡咯烷（6）单元。所有这些均含有作为增溶基团的4-十八烷基氧苯基取代基。发现微波（MiW）辅助加热对于可溶性MWNT效率很高，通过热重分析确定200℃MiW加热仅2小时后，添加的基团数量在相同范围内与在可溶性和不溶性MWNT常规加热100-120小时后获得的结果相同。溶解度是成功进行MiW加热反应的关键特征。与常规加热的反应相比，在MiW加热的反应中，不溶于反应介质的MWNTs产生的加合物要少得多。吡咯烷单元在MWNTs的最外层上的位置和均匀分布已通过对4个用金纳米颗粒处理并充分洗涤以除去吸附在MWNTs非官能化部分上的金颗粒的透射电子显微镜分析进行了验证。

  The present invention provides a surface-crosslinking process of a water-absorbent resin to obtain a water-absorbing agent which has high absorption speed and excellent absorption capacity under a load (a water-absorbent resin which has specific or larger values of properties). In a process comprising the step of adding a crosslinking agent to a dry water-absorbent resin powder to thereby crosslink the neighborhood of its surface, the surface-crosslinking is carried out while the resin powder having a weight-average particle diameter of 200∼1,000 µm is pulverized.
