using selected organic reactions. As expected, the resulting bifunctionalized PAF-1
showed excellent performances in catalyzing a series of cascade reactions.
In summary, the structure and property of POFs could be modified using the
post-synthetic approach. If the POFs have reactive groups, the modification is
relatively facile. Additionally, as indicated by the modification of PAF-1, the high
surface area and stability of POFs provide an indirect approach to achieve the target.
