Aryl(dicyclohexyl)phosphines were prepared by a catalytic C–P bond-forming cross-coupling reaction of haloarenes with dicyclohexylphosphine under heterogeneous conditions in water containing an immobilized palladium complex coordinated to an amphiphilic polystyrene–poly(ethylene glycol) resin supported di(tert-butyl)phosphine ligand.

Poly(ethylene glycol) methyl ether-grafted-graphene oxide (GO) was synthesized by a coupling reaction and formed inclusion complexes (ICs) after selective threading of the mPEG segments of the GO-mPEG through the cavities of α-cyclodextrins (α-CDs) units. The polypseudorotaxane structures of the as-obtained hydrogels were confirmed by X-ray diffraction, TGA, DSC, and SEM. The complexation of the mPEG segments with α-CDs and the hydrogen-bond interaction between CDs resulted in the formation of supramolecular hybrid hydrogels with a strong network. The resultant hybrid hydrogels were found to be thermo-responsive, and could be applied as a promising drug delivery system.
