This review provides a complete overview of the progress towards implementation of CuI-nanoclusters in functional materials and devices.

Nonlinear optical properties, upconversion and lasing in metal–organic frameworks

The building block modular approach that lies behind coordination polymers (CPs) and metal–organic frameworks (MOFs) results not only in a plethora of materials that can be obtained but also in a vast array of nonlinear optical properties that could be aimed at.

Symmetrically Related Construction and Optical Properties of Two Noncentrosymmetric 3D Iodides of d(10) Cation (Cu(+), Ag(+)) Based on the N-Benzylpyridinium and Its Supramolecular Interactions

Two noncentrosymmetric compounds, namely, [N-Bz-Py]2[Cu6I8] (1) and [N-Bz-Py]4[Ag9I13] (2) (N-Bz-Py(+) = N-benzylpyridinium), with three-dimensional open frameworks, were synthesized solvothermally via in situ benzylation of pyridine. 1 is constructed from 3-connected Cu3I7 secondary building units (SBUs) with chiral (10,3)-a topology, while the occluded N-Bz-Py(+) forms a complementary supramolecular (10,3)-a net via π-π interactions. 2 is characteristic of acentric connections of trimeric Ag3I8 and hexamer Ag6I12 SBU, while N-Bz-Py(+) in the channels aggregates into asymmetrically supramolecular chains via π-π interactions. Remarkable structural correlations imply the unique amplification and transfer of asymmetric information from V-shaped N-Bz-Py(+) to organic supramolecular nets and inorganic frameworks, which are confirmed by their second harmonic generation responses. Adsorption spectra reveal their semiconductive nature (2.52 eV for 1 and 3.02 eV for 2) and interesting reversible thermochromism for 1 based on the intermolecular charge transfer.

A twofold interwoven two-dimensional→two-dimensional (2-D→2-D) cluster-organic network based on the [Cu2I2] cluster and the 4,4'-(diazenediyl)dipyridine ligand: poly[[μ2-4,4'-(diazenediyl)dipyridine]-μ2-iodido-copper(I)]

In the polymeric title compound, [CuI(C(10)H(8)N(4))](n), the Cu(I) atom is in a four-coordinated tetrahedral geometry, formed by two I atoms and two pyridine N atoms from two different 4,4'-(diazenediyl)dipyridine (4,4'-azpy) ligands. Two μ(2)-I atoms link two Cu(I) atoms to form a planar rhomboid [Cu(2)I(2)] cluster located on an inversion centre, where the distance between two Cu(I) atoms is 2.7781 (15) Å and the Cu-I bond lengths are 2.6290 (13) and 2.7495 (15) Å. The bridging 4,4'-azpy ligands connect the [Cu(2)I(2)] clusters into a two-dimensional (2-D) double-layered grid-like network [parallel to the (10-2) plane], with a (4,4)-connected topology. Two 2-D grid-like networks interweave each other by long 4,4'-azpy bridging ligands to form a dense 2-D double-layered network. To the best of our knowledge, this interwoven 2-D→2-D network is observed for the first time in [Cu(2)I(2)]-organic compounds.

A two-dimensional silver–iodide organic network constructed from a unique [Ag6I6] hexagonal prism-based one-dimensional column motif

A novel two-dimensional coordination polymer, poly[[μ2-1,3-bis(2-methyl-1H-imidazol-1-yl)propane]di-μ4-iodido-di-μ3-iodido-silver(I)], [Ag4I4(C11H16N4)]n, (I), has been synthesized by solvothermal reaction of AgNO3, KI and 1,3-bis(2-methyl-1H-imidazol-1-yl)propane (bmimp). In (I), the two unique AgIcations have AgNI3and AgI4four-coordinated tetrahedral geometries. The bmimp ligand has imposed twofold symmetry. The AgIcations and iodide anions form a unique one-dimensional polymeric column motif incorporating [Ag6I6] hexagonal prisms, which are then connected by bmimp ligands to form two-dimensional organic–inorganic layers. The layers are arranged in parallel in anABABfashion and are packed into the resultant three-dimensional supramolecular framework by van der Waals interactions.
