“…While in the case of CP 2 , the calculated energy barrier was found 38.42 K and relaxation time 4.60×10 −8 s (Figure S11 d). The U eff / k B value of CP 1 is comparable with most of the reported 2D coordination polymers (Table S5) and phosphonate‐carboxylate based 2D network reported in the literature …”

Three lanthanide-based two-dimensional (2D) coordination polymers (CPs), [Ln(L)(H 2 O) 2 ] n ,{ H 3 L = (HO) 2 P(O)CH 2 CO 2 H; Ln = Dy 3 + (CP 1), Er 3 + (CP 2)} and [{Gd 2 (L) 2 (H 2 O) 3 } . H 2 O] n ,( CP 3)w ere hydrothermally synthesized using phosphonoacetica cid as al inker.S tructural features revealed that the dinuclear Ln 3 + nodes were present in the 2D sheet of CP 1 and CP 2 while in the case of CP 3, nodes were furtherc onnected to each other forminga chain-type arrangement throughout the network. The magnetic studies show field-induced slow magnetic relaxation property in CP 1 and CP 2 with U eff values of 72 K( relaxation time, t 0 = 3.05 10 À7 s) and 38.42 K( relaxation time, t 0 =4.60 10 À8 s) respectively.A b-initio calculations suggest that the gt ensoro fK ramers doublet of thel anthanide ion (Dy 3 + and Er 3 + )i ss trongly axial in nature which reflects in the slow magnetic relaxation behavior of both CPs. CP 3 exhibits as ignificant magnetocalorice ffect with ÀDS m = 49.29 Jkg À1 K À1 ,o ne of the highest value among the reported 2D CPs. Moreover, impedance analysis of all the CPs show high proton conductivity with values of 1.13 10 À6 Scm À1 ,2 .73 10 À3 Scm À1 and 2, 6.27 10 À6 Scm À1 for CPs 1-3,r espectively,a th igh temperature (> 75 8C) and maximum 95 %relative humidity (RH).[a] S.

“…Upon estimation of BET SSAs, the Rouquerol criteria were followed, while all of the data points were employed to calculate Langmuir SSAs. The BET SSAs exceed those of some published LOFs such as PCN-17(Yb) (820 m 2 g –1 ), ZJNU-63 (813 m 2 g –1 ), UTSA-61 (770 m 2 g –1 ), MIL-103 (730–930 m 2 g –1 ), PCM-15 (674 m 2 g –1 ), PCM-16 (620 m 2 g –1 ), [DyL] [582 m 2 g –1 ; L = tris(4-carboxylatephenyl)phosphine oxide], MOF-76 (264–334 m 2 g –1 ), and [NdL] (153 m 2 g –1 ; L = 4,4′,4″,4′″-silanetetrayltetrabenzonate) . Density functional theory (DFT) calculations revealed that the pore size is mainly distributed at 10.0 Å (Figure a, inset), which is comparable to the channel size.…”

Lanthanide–Organic Frameworks Featuring Three-Dimensional Inorganic Connectivity for Multipurpose Hydrocarbon Separation

et al. 2021

Implementation of lanthanide−organic frameworks (LOFs) as solid adsorbents has been frequently handicapped by their permanent porosity being difficult to establish owing to the remarkable flexibility and diversity of lanthanide ions in terms of coordination number and geometry. Construction of robust LOFs with permanent porosity for industrially important hydrocarbon separation will greatly expand their application potential. In this work, by distributing N and O donors into an m-terphenyl skeleton, we rationally synthesized a heterofunctional linker, and constructed a pair of isostructural LOFs. Due to the inclusion of a rarely observed three-dimensional metal−carboxylate backbone serving as a highly connected inorganic secondary building unit, their permanent porosities were successfully established by diverse gas isotherms. They can be applied as separating media not only for natural gas purification and removal of carbon dioxide from C 2 hydrocarbons but also more importantly for single-step ethylene (C 2 H 4 ) purification from a three-component C 2 H n mixture during the adsorption process. The latter separation is very challenging and has been less reported in the literature. This work provides a unique example of LOFs featuring three-dimensional inorganic connectivity applied to multipurpose hydrocarbon separations.
