Poly(isophthalic acid)(ethylene oxide) as a Macromolecular Modulator for Metal–Organic Polyhedra

Abstract

A new strategy was developed by using a polymer ligand, poly(isophthalic acid)(ethylene oxide), to modulate the growth of metal-organic polyhedra (MOP) crystals. This macromolecular modulator can effectively control the crystal habit of several different Cu24L24 (L = isophthalic acid derivatives) MOPs. The polymer also directed the formation of MOP structures under reaction conditions that only produce metal-organic frameworks in the absence of modulator. Moreover, the polymer also enabled the deposition of MOP crystals on glass surfaces. This macromolecular modulator strategy provides an innovative approach to control the morphology and assembly of MOP particles.

“… 28 On the other hand, MOP counterparts, built from metal–organic nanosized cages (1–3 nm) with intrinsic pores, can be potentially useful in energy applications such as gas separation. 29 Cohen, 30 Nitschke, 31 and Johnson 32 , 33 have used polymeric ligands together with cage moieties for the synthesis of 3D polymeric frameworks ( Fig. 1b ).…”

Coordination Properties of Hydroxyisophthalic Acids: Topological Correlations, Synthesis, Structural Analysis, and Properties of New Complexes

“…For example, cage-like entities show adsorption of N 2 , H 2 , O 2 , Ar, CO 2 , CH 4 . [32,34] For example, 0D cage [Mo 24 (H 2 O) 12 (DMPU) 12 (5-hip) 24 ] (XUQLEC) was obtained by solvothermal reaction in N,N'-dimethylpropyleneurea (DMPU) at 85°C of Mo 2 (O 2 CCF 3 ) 4 with an excess of H 2 -5-hip. [35] The voluminous DMPU coordinated to the dimer {Mo 2 (CO 2 )} only from one side that promoted assembling cuboctahedral coordination cages with 5-OH group of the angular linkers on the same convex side of the surface (Figure S29).…”

Defect‐Free Mixed‐Matrix Membranes with Hydrophilic Metal‐Organic Polyhedra for Efficient Carbon Dioxide Separation

“…Metal‐organic polyhedra (MOPs) self‐assembled by metal ions and organic ligands are an emerging supramolecule with robust discrete structures and tailorable molecular cavities for a variety of applications such as biomedicine, catalysis, gas separation, etc. Recently, the chemical modification of organic ligands in MOPs makes them soluble in specific solvents, which open up interesting applications as homogenous catalysts, drug delivery cargo and ion transport membranes, etc.…”
