Robust crosslinked capsules are produced from water droplets stabilized by oil/water interfacial assembly of norbornene‐functionalized CdSe/ZnS core–shell quantum dots that can be crosslinked by ring‐opening metathesis polymerization (see Figure). The mechanical integrity of the capsules is maintained after removal of the interface. An amphiphilic polyethylene glycol‐substituted ruthenium benzylidene catalyst proved ideal for this interfacial polymerization.
