trannulene derivatives of fluorofullerene C 60 F 18 possessing six carboxylic or ammonium ion groups have been synthesized and spectrally characterized. The stability of emerald-green aqueous solutions of these compounds was investigated. A novel synthetic route was developed for a step-by-step derivatization of C 60 F 18 with different organic C―H acids that yielded nonsymmetrically substituted C 60 F

Compositions and methods related to targeted carbon nanostructures. More particularly, targeted carbon nanostructures comprising: a C
n
, a cross-linker, and a targeting agent, wherein C
n
refers to a fullerene moiety or nanotube comprising n carbon atoms. One example of a method may involve a method for imaging comprising: contacting a targeted carbon nanostructure and a cell; allowing the cell to internalize the carbon nanostructure; and detecting the presence of internalized carbon nanostructures.
four bifullerene molecules in a supposedly bent conformation, their amphiphilic equivalents underwent a hierarchical two‐step assembly process towards larger spherical and even rod‐like structures. The data suggest that the hierarchical assembly process is driven by hydrophobic interactions of preformed tetrameric elementary micelles.
合成了一系列新型功能化哑铃形双富勒烯,其中两个 C 60的[5.0]五加合物通过环状双丙二酸酯共价连接。这些二聚化合物携带各种亲水性和疏水性附加物的组合,在水溶液中自组装成具有不同结构复杂性的超分子结构,如低温透射电子显微镜(cryo-TEM)所观察到的。对图像数据的详细分析揭示了前所未有的分层聚合行为。完全亲水取代的双富勒烯形成了高度单分散的小寡聚基本胶束群,仅由三或四个呈弯曲构象的双富勒烯分子组成,而它们的两亲等价物经历了分层两步组装过程,形成更大的球形甚至棒状结构。数据表明,分层组装过程是由预先形成的四聚体基本胶束的疏水相互作用驱动的。

A series of amino-substituted methanofullerene derivatives were prepared by mono, tris-, and hexa Bingel-Hirsch reactions using an N-protected malonate derivative, Upon scission of the protecting groups, the e,e,e-tris- and octahedral T-h hexa-methano amino fullerenes were found to be among the most water-soluble fullerene derivatives yet prepared. He-3 NMR data on corresponding adducts of He-3@C-60 helped verify the assigned structures. UV spectral studies confirmed the influence of aggregation on solubility of these adducts in water.
