摘要
We derive an analytical form for the effective interaction forces between two solvophobic solutes, mediated by the solvent. The effective force is attractive for short ranges, which decreases linearly with surface-to-surface separation s between the solutes and repulsive in the long range falling off as 1/s(4). The attraction originates from the unbalanced Laplace force at the liquid-gas interface, generated by the repulsive interaction with the solvent particles. We illustrate with the Lennard-Jones solvent that the effective forces capture experimental observations on hydrophobic species in aqueous solution. We discuss the general implication of our results in the context of hydrophobic collapse.
