Rational Design of Porous Coordination Polymers Based on Bis(phosphine)MCl_2 Complexes That Exhibit High-Temperature H_2 Sorption and Chemical Reactivity

摘要

MCl_2 complexes of a new p-carboxylated 1,2-bis(diphenylphosphino)benzene ligand are effectively utilized as tetratopic building blocks to prepare isostruc-tural porous coordination polymers with accessible reactive metal sites (M = Pd, Pt). The crystalline materials exhibit unusual and fully reversible H2 sorption at 150℃, Post-synthetic reactivity is also possible, in which Pt-Cl bonds can be activated to provide organometallic species in the pores.
