“…12 In recent years, more attention has been paid to fullerene dimers because their unique physical and chemical properties provide intriguing possibilities as model compounds for nano-and polymer science, and offer potential access to novel molecular electronic devices. 13,14 In this respect, a series of fullerene dimers have been produced, such as C 120 , 15 the carbon-bridged dimers: C 121 , [16][17][18][19] C 140 , C 131 , 20 and C 122 , 15,19,21 and the heteroatom bridged dimer: C 120 O, [22][23][24] which could be used as the basic units of fullerene chain structures. The simplest fullerene dimer C 120 , (C 60 ) 2 , has been prepared by solid-state 25 and by chemical methods.…”

We have performed DFT calculations to devise some possible fullerene dimers (from C60 and C80) connected through C24 and C36 bridge cages with the face-to-face linking model. The fullerene dimers with C36 bridges have lower binding energies and greater HOMO-LUMO gaps than those of the fullerene dimers with C24 bridges. Also, the replacement of C60 cages with C80 ones always leads to an increase in binding energies and HOMO-LUMO gaps in these systems. Dimerization of C60 and C80 fullerenes with C24 and C36 results in a significant decrease in antiaromaticity of the antiaromatic cages C24 and C80, and an increase in the aromaticity of the aromatic cages C36 and C60. Therefore, DFT results indicate that those fullerene dimers involving the initially harshly antiaromatic C24 or C80 cages are more energetically favorable configuration than the fullerene dimers involving the aromatic C36 and C60 cages.

Semiempirical quantum mechanical PM5 method is employed to investigate the electronic properties of alkali metal dimers. A model molecule of 2C 60 and 2C 60 -X are presented; where X is Be, Mg and Ba respectively. Results indicate that Fullerene dimmer (2C 60 ) has a molecular point group corresponding to D2h. The molecular point group is changed into Cs point group corresponding to 2C 60 -X, which reflects a possible change in the symmetry. Results indicate also that alkali's increases the calculated total dipole moment while both ionization potential and binding energy is slightly decreased. Final heat of formation is increased with temperature; while it increases from 2C 60 to 2C 60 -Mg followed by sharp decrease in case of 2C 60 -Ba. This reflects the thermal stability of the studied Alkali's dimmer as compared with 2C 60 except for 2C 60 -Ba. The calculated ionization potential and binding energy are decrease as the number of alkali atoms (X) increased. As a result of alkali the characteristic bands of C 60 is shifted toward lower wavenumbers with noticeable broadening.
