POMbasics-2022. The first POMbasics 2022 summer school “Polyoxometalate Chemistry for Fundamentals and Applications” was held in La Rochelle from June 13 to 15, 2022. Organized jointly by the E-POM team of the IPCM of Sorbonne University and the MIM team from ILV of UVSQ, this international event brought together more than 55 participants from universities and laboratories from seven European countries (Spain, Italy, Germany, Belgium, United Kingdom, France, Austria). Deliberately ambitious, the program of this school aimed to make the link between the fundamental aspects of the chemistry of polyoxometalates and the major societal issues (energy, health & environment) for which this family of compounds can provide credible solutions. This event is supported by the IRN-CNRS “SMART Molecular Oxides” network and the LabEx MiChem. It has also received the CNRS label “Ecole Thématique”. https://www.irn-pom.uvsq.fr
