Fullerene doped monoliths

Another route to fabricate fullerene doped monoliths has been shown by Peng et al. (2001), which successfully prepared crack free, transparent fullerene glasses oflarge dimensions (up to 60 mm) from sol-gel mixtures of aminated Cgo derivatives and tetraethyl orthosilicate (TEOS). The aminated fullerene derivatives have been synthesized by amination reactions of Ceo with 6-amino-l-hexanol, cyclohexylamine, 2-(2-aminoethoxy)ethanol, and 3-aminopropyltriethoxysilane to prepare derivatives with the molecular structures H C6o[NH(CH2)6oH]jt, H C6o(NH-cyc/o-C6Hn)je, Hjj,C6o[NH(CH2CH2o)2H], and H (C6o[NH(CH2)3Si(OCH2CH3)3]i . A silica network with covalently bonded amine fullerene derivatives has been obtained, as shown in Figure 23-3.
