Simple Modification in Hexakis-Addition for Efficient Synthesis of C_60-Centered Dendritic Molecules Bearing Multiple Aromatic Chromophores

摘要

In the templated hexakis-addition reaction of malonic esters with C_60 to prepare dendritic macromolecules that are terminated symmetrically with 12 derivatized pyrenes,a simple modification to use a much larger excess of the bromination agent resulted in dramatic increases in the product yields.
