Mechanochemistry is a “green” synthetic method, which is already used in an impressive range of research areas, ranging from catalysis to pharmacy, as well as crystal engineering and materials science. Although the interest in this method is continuously growing for elaborating complex molecules and materials, the reaction mechanisms involved with these syntheses in the solid state are still poorly understood, thus hampering its further development towards the production of novel compounds.
Within the ICGM, we have recently developed our own operando platform, specifically adapted for ball-milling, in order to follow and decipher the processes involved in solid phase syntheses. Such operando techniques (Raman spectroscopy, temperature monitoring and/or acoustic measurements) allow chemical and physical information to be recorded during the milling. In this seminar, a few examples of operando studies will be exposed, involving the synthesis of zinc-terephthalate networks, as well as simpler cocrystals.
