The addition of poly(1,3-cyclohexadiene) (PCHD) carbanion to fullerene-C-60 (C-60) was examined using poly(1,3-cyclohexadienyl)lithium (PCHDLi), PCHDLi/1,4-diazabicyclo[2,2,2]octane (DABCO), and PCHDLi/N,N,N',N'-tetramethylethyleiiediamine (TMEDA). The reactivity of PCHD carbanions was in the order of PCHDLi > PCHDLi/DABCO > PCHDLi/TMEDA, regardless of the polymer main chain structure. PCHDLi, PCHDLi/DABCO, and PCHDLi/TMEDA in toluene formed (sigma-structures, sigma- and pi-structures, and pi-structures, respectively. The degree of localization on the terminal carbanion was a main factor for control of this addition reaction. In addition, all 1,2-cyclohexadiene (1,2-CHD) unit sequences contributed to preventing the addition reaction. That is, large steric hindrance of the polymer main chain was another important factor to control the addition reaction.
