“…Based on the unique features of HMOFs as catalysts andt he above catalysis results, ap ossible cooperatively catalytic mechanism was proposed. [39][40][41][42][43][44][45][46] First, an epoxide is adsorbed and activatedb yt he Lewis acid dual metallicA g I and Tb III centers. Then, the ring-opening step is driven by the activation effect of the dual metallic Ag I and Tb III centers ites andt he epoxidei s attacked by the halogen ion on the less hindered side.…”

The coordination preference of different metal ions and ligandsh ave an immense influenceo nt he constructions of functional MOF materials.I nt his work, two new monometallicc omplexes,n amely [Ag(HL)(bipy) 0.5 ]( 1)a nd {[Tb(L) 1.5 (H 2 O)]·4H 2 O} n (2)( bipy = 4,4-bipyridine), have been synthesized successfully by employing abifunctional 2-(imidazol-1-yl)terephthalic acid (H 2 L) ligand.A fter that, two new different heterometallic-organic frameworks (HMOFs),were obtained from complexes 1 and 2 as the precursors based on ar ational stepwisec onstruction strategy and the theoryo fh ard and soft acids and bases (HSAB principle), respectively.T he HMOFs bearing dual metallic catalytic sites (Tb and Ag) can be used as heterogeneous catalysts without losing performance for the chemical fixation of CO 2 with epoxidesi ncluding the sterically hindered epoxides,d emonstratings ome of the highest reported catalytic activity values. This work may provideanew synthetic route toward tailoringnew HMOFs with excellent catalytic activity. Results and Discussion Structure descriptionSingle-crystal structure analysis reveals that complex 1 is ad iscrete monometallic molecule. It belongs to the monoclinic C2/ c space group, and itsa symmetricu nit consists of one Ag I ion, one HL À ligand, and half ab ipy molecule. The Ag I ion is linearly coordinatedw ith Na toms from HL À and bipy (Figure 1), the AgÀNb ond lengths are 2.105 and 2.131 ,r espectively.[a] J.

“…In the past decades, the various homogeneous catalysts have been developed for chemical fixation of carbon dioxide to form cyclic carbonates [14][15][16], such as alkali metal salts [17,18], transition metal complexes [19][20][21][22], metal organic frameworks [23][24][25][26], organic bases [27,28], N-heterocyclic carbene [29], quaternary ammonium salts [30][31][32][33], quaternary phosphonium salts [34,35], organocatalyst [36,37], and ionic liquids [38][39][40][41][42][43]. Most of them are efficient for cycloaddition of carbon dioxide and epoxide, but the cost is high for product separation and/or catalyst fabrication.…”

A series of immobilized protic ionic liquids were prepared and used as catalysts for chemical fixation of carbon dioxide with epoxide to form cyclic carbonate. The effects of reaction temperature, carbon dioxide pressure and the loading of immobilized ionic liquid on the synthesis of cyclic carbonate from carbon dioxide and epoxide were investigated. Under the optimized reaction conditions, PS-ImHI showed the highest catalytic activity, and propylene carbonate was yield to 98.1% with more than 99% of selectivity. In the coupling reaction of carbon dioxide and epoxide, the immobilized ionic liquids showed high stability and could be reused ten times and used in a continuous flow reaction with a fixed-bed reactor for more than 120 h without loss of catalytic activity.
