Lipophilic methyl‐substituted cyanobiphenyls can be considered as molecular salmon that jump out of the condensed phase, but are limited by an increase in size of their rigid core. The concept of cohesive free‐energy densities applied to melting processes correlates the molecular volumes of the constituents with the macroscopic enthalpic and entropic changes that accompany the phase transitions of the bulk materials.
