 Abstract: We report the observation of structural changes in an axially chiral molecule, biphenyl-2-carboxaldehyde, due to aggregation with water. Using high-resolution broadband rotational spectroscopy we find that two water molecules link opposite sides of the molecule, resembling a water wire. We show that this effect can be explained by a cooperative rearrangement of both molecule and a water dimer. Hydrogen bonding interactions are shown to change the original structure upon aggregation of water. This phenomenon is insightful on the role of microsolvation in assisting structural morphing of stereo-selective chiral molecular systems.
