An N-heterocyclic carbene-based palladium complex was successfully immobilised on the inner surfaces of hollow silica nanospheres. The external surfaces of these spheres were functionalised with a corona-canopy to produce a Type I porous liquid. To confirm the successful immobilisation of the catalytic precursor, the porous liquid system was explored using the Heck reaction as a model reaction. This work demonstrated that homogeneous catalysts can be successfully immobilised within porous liquids in principle and that the approach used could be readily adapted for the immobilisation of other systems.

I型多孔液体中均相钯催化剂的固定化

一个Ñ -杂环卡宾基于-钯复合物成功地固定中空二氧化硅纳米球的内表面上。这些球的外表面用电晕冠进行功能化，以产生I型多孔液体。为了确认催化前体的成功固定，使用Heck反应作为模型反应探索了多孔液体系统。该工作证明，原则上均相催化剂可以成功地固定在多孔液体中，并且所使用的方法可以很容易地适用于其他系统的固定。
