  2. 目录 • 1、苝酰亚胺研究(Wasielewski小组) • 2、苝系衍生物的新应用研究

  3. (Tamar van der Boom,Ryan T. Hayes,Wasielewski R, et al. Charge Transport in PhotofunctionalNanoparticles Self-Assembled from Zinc 5,10,15,20-Tetrakis(perylenediimide)porphyrin Building Blocks. J.AM.CHEM.SOC,2002,124:9582-9590.) 一、苝酰亚胺的研究 海湾处取代基的引入使PDI两个萘环之间由于空间张力的原因而发生螺旋形的扭曲

  4. 无论是固体薄膜或是液体溶液,它都会因为苝酰亚胺基团之间强的π-π堆积作用而自组装成纳米粒子,光致激发形成3.2 ps的电荷分离态。

  5. 一、苝酰亚胺的研究 Photoinitiated Charge Transport in Supramolecular Assemblies of a 1,7,N,N’-Tetrakis(zinc porphyrin)-perylene-3,4:9,10-bis(dicarboximide), R. F. Kelley, W.-S. Shin, B. Rybtchinski , and M. R. Wasielewski, J. Am. Chem. Soc. 129, 3173-3181 (2007).

  6. 在甲苯溶液中,ZnTPP-PDI4自组装形成具有五个分子的单分散聚集体(ZnTPP-PDI4)5,ZnTPP-PDI不会形成聚集体, (ZnTPP-PDI4)5形成4.8ns的电荷分离态,ZnTPP-PDI形成3.0ns的电荷分离态。 (ZnTPP-PDI4)5SAXS数据建模图

  7. 一、苝酰亚胺的研究 Ultrafast Aggregate-to-Aggregate Energy Transfer within Self-assembled Light-Harvesting Columns of Zinc PhthalocyanineTetrakis(perylenediimide), X. Li, L. E. Sinks, B. Rybtchinski, and M. R. Wasielewski, J. Am. Chem. Soc. 126, 10810-10811 (2004).

  8. SAXS数据建模的聚集体结构图(ZnPcIm4-PDI4)7 选择性激发苝酰亚胺,经单线态-单线态能量转移,将能量转移至中心的锌酞菁上。

  9. 一、苝酰亚胺的研究 Combining Light-harvesting and Charge Separation in a Self-assembled Artificial Photosynthetic System based on PerylenediimideChromophores, B. Rybtchinski, L. E. Sinks, and M. R. Wasielewski, J. Am. Chem. Soc. 126, 12268-12269 (2004).

  10. (PDI-PDI4)2SAXS数据建模图 能量转移只发生在二聚体中,分散的单体不会发生能量转移,同时在单体也不会出现电荷分离态。

  11. 二、苝系衍生物新应用研究 Competition between Singlet Fission and Charge Separation in Solution-Processed Blend Films of 6,13-Bis(triisopropylsilylethynyl)pentacene with Sterically-Encumbered Perylene-3,4:9,10-bis(dicarboximide)s, C. Ramanan, A. L. Smeigh, J. E. Anthony, T. J. Marks, and M. R. Wasielewski, J. Am. Chem. Soc.134, 386-397 (2012).

  12. 二、苝系衍生物新应用研究

  13. The Potential of PeryleneBisimide Derivatives for the Solubilizationof Carbon Nanotubes and Graphene. Claudia Backes , Frank Hauke , and Andreas Hirsch . Adv. Mater. 2011, XX, 1–14
