Layer-by-layer deposition is a widely used method for surface functionalization. It is shown here that up to 58 covalently linked molecular layers could be assembled in 20 min at room temperature on a silicon wafer by the layer-by-layer click reaction of a divalent triazolinedione and a trivalent diene. The layer growth was found to be linear. The multilayers were analyzed by ellipsometry, atomic force microscopy, and X-ray photoelectron spectroscopy.
