Abstract:
The characteristic electronic absorption of a zwitterionic molecule arising from an intramolecular charge‐transfer transition observed in the solution and the bulk solid states vanishes completely when the molecules are assembled into mono‐ and multilayer Langmuir–Blodgett films (see figure). Microscopy and spectroscopy investigations and computational modeling provide insight into this remarkable phenomenon.
