Preparation of Microporous Melamine‐based Polymer Networks in an Anhydrous High‐Temperature Miniemulsion

We report the first example of a successful preparation of a microporous organic polymer within the droplet phase of an inverse non‐aqueous miniemulsion. Stable nanoparticles with enhanced specific surface area could be obtained despite the harsh conditions regarding reaction temperature (180 °C) and time (72 h) needed for building melamine‐based Schiff base networks. Our new flexible method can in principle be applied to other water‐sensitive protocols suitable for the bulk synthesis of MOPs that are based on Friedel‐Crafts, Sonogashira‐Hagihara or Yamamoto chemistry.
