<jats:title>Abstract</jats:title><jats:p>We have observed the inversion of the solvation environment of a one‐dimensional solid by low‐temperature scanning tunneling microscopy. Adsorption of 3‐methoxy‐9‐diazofluorene on Ag(111) yields highly oriented supramolecular chains, which are then exposed to water molecules. The annealing of dry and water‐decorated chains results in diametrically opposed outcomes. While the former simply leads to an increase in chain length and number, the latter results in a complete loss of order and produces water clusters decorated with the organic molecule.</jats:p>
