摘要

Reorganization energies X ofisomers of' hydrogenated fullerenes, C_(70)H_n (n = 4, 6, 8), are investigated by the density functional theory (B3LYPI6-311G~(**)). The smallest value of λ (λ_(min)) of C_(70)H_4 is 74 meV and is smaller than those 0f C_(70)H_2 (79 meV) and C_(60)H_4 (83 meV). λ_(m!n) of C_(70)H_6 and C_(70)H_8 are 72 meV and 74 meV, respectively. Addition of H atoms to [6,6]-ring fusion generally gives smaller X than that to [5,6]-ring fusion. Hydrogenation can reduce λ_(min) of C_(70) materials and the result that C_(70)H_6 has the smallest λ_(min) is same with the result of hydrogenation of C_(60)
