Rules of fullerene polarizability

Polarizability in Astrochemical Studies of Complex Carbon-Based Compounds

“…The dependence of α­(C 60 H n ) on the number of hydrogen atoms is not monotonic: the mean polarizability increases up to n = 18 and then goes down for three isomers of C 60 H 36 (such an effect of polarizability depression is typical for fullerene exohedral derivatives). It means that the detection of highly hydrogenated fullerenes in an interstellar medium is more reasonable than the detection of hydrogen-poor C 60 H n .…”

“…The latter quantity depends on the molecular polarizability. As C 70 is more polarizable than C 60 (∼100 vs ∼80 Å 3 ), it quenches more efficiently.…”

“…Previously, we systematically studied the polarizability of fullerene derivatives and stressed its crucial role for chemistry and materials science . For example, it reflects the features of interacting fullerene adducts with irradiation in organic solar cells , and molecular switches or screening atoms and small molecules trapped inside the fullerene cages. , Expectedly, the polarizability of fullerenes was invoked to analyze the chemical properties of these species.…”

“…In this section, we hypothesize about interstellar and circumstellar processes using the polarizability. We focus on fullerenes and PAHs, as polarizability plays crucial role in their chemistry. , …”

“…Additionally, it is an easily computable molecular property. We efficiently used it to predict the physicochemical behavior and reactivity of fullerene compounds , and recently found it useful for theoretical astrochemistry studies (see our key work in ref ).…”
