Fullerenes: Aspects, prospects, limits and speculations

Abstract

In ten years fullerenes have gone from structural speculation to single crystals as ever more efficient preparation and separation procedures have been developed. Today fullerene solids comprise an extensive family of all‐carbon materials assembled from a large number of different ∼ 1 nm sized subunits. We discuss a number of issues related to the unique electronic and geometric structure of these molecular subunits.

Information Entropy of Fullerenes

“…The C 2 loss is another important reaction among the processes under fullerene synthesis. ,− Two processes were theoretically studied: , The last one is thermodynamically more favorable. As previously calculated, Δ E R (9) = +1080.2 (ref ) and Δ E R (10) = +782.9 kJ mol –1 (ref ), so C 60 has higher stability against the C 2 loss. These reactions are good examples to demonstrate the formalism for calculation of changes in information entropies Δ h R .…”
