Amphiphilic molecules, such as phospholipids and surfactants, self–assemble in water to form various aggregation structures such as bilayers. However, it is not understood whether hydration states of the molecules have roles in the self–assembly behavior or water is just a solvent. In the present study, we observed the hydration state of phospholipid bilayers using the terahertz spectroscopy, with which even weakly bound water is included as a hydration water. We found the long–range hydration states strongly depend on the chemical structures of the headgroups, and the change in the self–assembly structures from a bilayer is affected by the long–range hydration states. It can be said that water have crucial roles for the self–assembly of soft matters and bio molecules.
