How will the dichlophenyl group affect the geometric structure, electronic properties, and static linear polarizability of La@C72?

Molecular structures of Pr@C72 and Pr@C72(C6H3Cl2): a combined experimental–theoretical investigation

The carbon-cage structure of the lowest-lying Pr@C₇₂ and its dichlorophenyl-functionalized derivative is C₂(10612)-C₇₂.

Polarizability as a landmark property for fullerene chemistry and materials science

The review summarizes data on dipole polarizability of fullerenes and their derivatives, covering the most widespread classes of fullerene-containing molecules (fullerenes, fullerene exohedral derivatives, fullerene dimers, endofullerenes, fullerene ions, and derivatives with ionic bonds).

DFT calculations on the structural stability and infrared spectroscopy of endohedral metallofullerenes

Endohedral metallofullerenes M@C(24) (M = Li(0/+), Na(0/+), K(0/+), Be(0/2+), Mg(0/2+) and Ca(0/2+)) with different spin configurations have been systematically investigated using the hybrid DFT-B3PW91 functional in conjunction with 6-31 G(d) basis sets. Our theoretical studies show that Li@C(24), Be@C(24), Be(2+)@C(24), and Mg(2+)@C(24) are energetically favorable. In these endohedral metallofullerenes, only the encapsulated Be and Ca atoms can donate the electrons to the cage. With exception of Be(2+)@C(24), the energy gaps of other charged compounds are larger than that of corresponding neutral compounds. We also find that some endohedral metallofullerenes have high energy gaps, but they are unlikely to show high thermodynamic stability. Additionally, the vibrational frequencies and active infrared intensities are also used as evidence to identify these endohedral metallofullerenes.
