“…We envisage that this metalation method can be used to achieve hierarchical self-assembly bearing open chelating sites, which has not been reached. Recently, the tripodal ligands tris(2-benzimidazolylmethyl) amine (L) and tris(2naphthimidazolylmethyl) amine have attracted our attention because of their chelating sites formed by four nitrogen atoms [34][35][36][37]…”

Single-crystal-to-single-crystal metalation of organic ligands represents a novel method to prepare metal–organic complexes, but remains challenging. Herein, a hierarchical self-assembly {(H12L8)·([N(C2H5)4]+)3·(ClO4−)15·(H2O)32} (1) (L = tris(2-benzimidazolylmethyl) amine) consisting of π-stacked cubes which are assembled from eight partially protonated L ligands is obtained. By soaking the crystals of compound 1 in the aqueous solution of Co(SCN)2, the ligands coordinate with Co2+ ions stoichiometrically and ClO4− exchange with SCN− via single-crystal-to-single-crystal transformation, leading to {([CoSCNL]+)8·([NC8H20]+)3·(SCN)11·(H2O)13} (2).

“…For example, Huang’s group reported perethylated pillar [ 6 ] arene, which acts as a candidate for I 2 capture [ 41 ], while Zhang and co-workers directly observed the ambiguous binding sites for I 2 in a mesoporous assembly of aluminum molecular rings [ 42 ]. Recently, we have successfully obtained a series of π -stacked porous assemblies based on metal complexes of tripodal tris(2-benzimidazolylmethyl) amine or tris(2-naphthimidazolemethyl) amine [ 43 , 44 ]. These achievements promoted us to synthesize porous assemblies based on metal complexes of tripodal ligands to explore high-performance adsorbents for I 2 capture.…”

Acquiring adsorbents capable of effective radioiodine capture is important for nuclear waste treatment; however, it remains a challenge to develop porous materials with high and reversible iodine capture. Herein, we report a porous self-assembly constructed by a cup-shaped PdII complex through intermolecular π···π interactions. This self-assembly features a cubic structure with channels along all three Cartesian coordinates, which enables it to efficiently capture iodine with an adsorption capacity of 0.60 g g−1 for dissolved iodine and 1.81 g g−1 for iodine vapor. Furthermore, the iodine adsorbed within the channels can be readily released upon immersing the bound solid in CH2Cl2, which allows the recycling of the adsorbent. This work develops a new porous molecular material promising for practical iodine adsorption.

“…Complementary functional groups may also be precisely placed in the pores of hetero-interpenetrated MOFs to deliver unique adsorption, catalysis and sensing applications. Although occasional examples of hetero-interpenetrated MOFs have been discovered serendipitously, 3,[9][10][11][12] their deliberate synthesis remains elusive. Recent computational studies have identified sub-lattices that are mutually compatible in silico, however these putative hetero-interpenetrated MOFs have not been experimentally realised.…”

Hetero-interpenetrated metal–organic frameworks

Interpenetrated metal-organic frameworks (MOFs) comprise two or more lattices that are mutually entangled. Interpenetration tunes the structures and pore architectures of MOFs to influence their interactions with guest molecules. Typically, the interpenetrating sublattices are identical. Heterointerpenetrated MOFs, in contrast, have sublattices that are different to one another. While they can be produced by serendipity, to develop a deliberate strategy for making hetero-interpenetrated MOFs we employed the cubic -MUF-9 framework as a host sublattice. -MUF-9 is able to template the secondary growth of a second, interpenetrating, sublattice in its pores to produce hetero-interpenetrated MOFs. In certain cases, the sublattices cannot be produced via standalone reactions and are observed here for the first time. Unique functional properties are enabled by hetero-interpenetrated MOFs such as asymmetric catalysis. We grew a catalytically-active sublattice inside -MUF-10, a chiral host. The chiral pore environment of the host imparts asymmetry on the catalytic activity of interpenetrating sublattice to give reaction products with an enantiomeric excess. This deliberate strategy for synthesizing hetero-interpenetrated MOFs opens new perspectives on framework structures and pore environments and allows unprecedented functional properties to emerge.
