A flexible approach for the fabrication of chemical gradients on different substrates is presented. The key idea of the approach is tuning the exchange reaction between a self‐assembled monolayer covering the substrate and a potential molecular substituent by electron irradiation. The figure shows water drops on a hydrophilicity gradient created using this method.
