Introduction of [60]Fullerenes onto Polymer Chains via Noncovalent Bonds 

This section discusses the scope of [60]fullerene-based polymer chemistry. These approaches may allow for the development, on a supramolecular level, of unprecedented architectures. Previous sections have dealt primarily with the self-assembly of the [60]fullerene and its derivatives as a result of microphase separation and subsequent formahon of huge [60]fullerene clusters driven by the weak noncovalent forces in the solid state, mesophase and water. To avoid microphase separation, the introduction of functionalized [60]fullerene derivatives into polymer main chains through noncovalent interactions is a very promising approach. The construction of fullerene-containing supramolecular polymers in organic solution is now presented. 

A molecule of uracil and a 2,6-diacylaminopyridine (DAP) form a heterodimer through complementary three-fold hydrogen bonding, and this has been used to 

Fullerene-containing supramolecular polymers based on DNA templating have been reported by Chu and coworkers [96]. Cationic [60]fullerene derivahves bind onto the DNA main chain through Coulombic interachons, which gives rise to the polymeric nano-array of [60]fullerene. Shinkai and coworkers have reported photocurrent generation in a supramolecular fullerene polymer [97]. A [60]fullerene/ porphyrin/DNA ternary complex is deposited on an ITO (indium tin oxide) electrode by oxidative polymerization of E DOT. The effechve photocurrent generation is observed by light excitation of the porphyrin. 

Multifunctional [60]fullerenes possessing eight pyridyl or morphohne moieties create strong ionic interactions with acidic polymers such as poly(styrenesulfonic
