Homogeneous catalysts of high activity and selectivity often face challenges in the separation from feedstocks products after reactions. In contrast, heterogeneous are easier to separate, usually at cost compromised catalytic performance. By designing capable switching between homogeneous states for catalysis separation, merits both could be synergistically combined. this study, a thermoresponsive 1,2,4-triazolium-based poly(ionic liquid) (PIL) was applied as temperature-switchable organocatalyst controlled synthesis porous organic cages methanol. Variation reaction temperature induced phase transition PIL, causing polymer chains dissolve or collapse methanol, thereby exposing shielding catalytically active sites proceed retard reaction, respectively. To note, sufficiently low temperature, PIL catalyst precipitated out its methanol solution separated by centrifugation filtration reuse, similar common catalysts. Such switchable recyclable properties polymeric will inspire design efficient adaptable hybrid nanoreactors liquid media.
