| Physical and Chemical Properties | According to the spherical hollow structure of the football ENE (C60) molecule, it can be inferred that it should have aromatic nature and be able to carry out the reaction of general polycyclic aromatic hydrocarbons, such as alkylation, reduction is performed to generate a hydride, etc. It is well known that aromatic hydrocarbons generally exhibit electron-rich reactions, which are easy to undergo electrophilic substitution reactions with electrophilic reagents, but C60 shows the reactivity of electron-deficient compounds, that is, it tends to obtain electrons, it is difficult to react with electrophilic reagents, and easy to react with Nucleophilic Reagents such as NH3 and metals. beshee believes that the chemical behavior of the football Olefin is more like an electron-deficient olefin, rather than an aromatic compound, because the hollow spherical structure of C60 enables it to react on both the inner and outer surfaces of the ball, from this, a variety of functional soccer ENE derivatives were obtained. Where the metal is contained inside the C60 cage, it is indicated by M @ C60, and where the metal and C60 react on the outer surface of the sphere, it is indicated by mnc60. It is known that some chemical reactions of C60 have been well characterized, including reactions with metals to form contained compounds, halogenation reactions, free radical reactions, etc. Since the olefin on the surface of the C60 sphere is in the position of the sphere surface, that is, it deviates from the plane of the general olefin, and the degree of deviation is 30 degrees, in this way, the olefin on The C60 surface actually satisfies the required geometry of the ligand before coordination with the metal, and is in an ideal spatial position. Coupled with the lack of electronic properties of the C60 ball, it is not yet completely determined which of the two factors is dominant. Cyclic voltammetry studies show that C60 can be highly reversible to C- 60 and C2-60, which indicates that the football may be a new generation of reversible battery materials. |
| In vitro study | High affinity of fullerene core for electron donors determines its ability to be a scavenger of free radicals. On the other hand, C60 molecule is able to absorb effectively UV and visible light with further transition to the first singlet excited state, then to a long-lived triplet excited state and subsequent energy transfer to molecular oxygen-yielding singlet oxygen with quantum yield close to 100%. |
