of diphosphine ligand constructed porous polymers with
stable and flexible frameworks have been successfully synthesized
under the solvothermal conditions from polymerizing the corresponding
vinyl-functionalized diphosphine monomers. These insoluble porous
polymers can be swollen by a wide range of organic solvents, showing
similar behavior to those of soluble analogues. Rather than just as
immobilizing homogeneous catalysts, these porous polymers supported
with Rh species demonstrate even better catalytic performance in the
hydroformylations than the analogue homogeneous catalysts. The sample
extraordinary performance could be attributed to the combination of
high ligand concentration and flexible framework of the porous polymers.
Meanwhile, they can be easily separated and recycled from the reaction
systems without losing any activity and selectivity. This excellent
catalytic performance and easy recycling heterogeneous catalyst property
make them be very attractive. These diphosphine ligand constructed
porous polymers may provide new platforms for the hydroformylation
of olefins in the future.
