In the present work it is shown that the well‐known α‐Keggin polyoxometalate, α‐PW 12 O 40 3− (PW), forms hybrid crystalline materials with industrial (neutral) polyethylene glycol oligomers (PEG) under mild conditions, that is, in aqueous medium and at room temperature. The formation of these materials originates from the spontaneous self‐assembly of PW with EO x with at least four EO units ( x ≥ 4). Addition of NaCl induces the collapse of the nanoassemblies and the formation of hybrid crystalline materials. More information can be found in the Full Paper by P. Bauduin et al. on page 8434.
