Layer‐by‐Layer self‐assembly on planar substrates of a Fe(II) metallo‐supramolecular coordination polyelectrolyte (MEPE) and poly‐(styrene sulfonate) (PSS) is investigated with a variety of surface sensitive techniques. Results from reflection‐absorption infrared (RAIR) spectroscopy and microgravimetry are in agreement with linear multilayer build‐up. Furthermore, RAIR spectroscopy indicates close to complete counter ion exchange during polyion deposition. The multilayers contain approximately 20 mass‐percent water under ambient conditions. Water uptake and loss is completely reversible. Annealing to 250°C in air does not affect the structural integrity of the film as demonstrated by XRR measurements.
