Study suggests that decaphenylbiphenyl is not a high-energy molecule, despite being crowded and seemingly strained
Perphenyl arenes are not as unstable as we think, according to a study by researchers in the US and Portugal. It found that intramolecular dispersion forces in decaphenylbiphenyl and 2,2′,4,4′,6,6′-hexaphenylbiphenyl compensate for the steric repulsion in these crowded molecules.
