Recent progress of d10 iodoargentate(I)/iodocuprate(I) hybrids: Structural diversity, directed synthesis, and photochromic/thermochromic properties

Polymorphic Copper Iodide Anions: Luminescence Thermochromism and Mechanochromism of (PPh4)2[Cu2I4]

“…These Cu-Cu distances lie in the range of values encountered in copper iodide compounds. 9,13,26 Nevertheless comparison with the value of the sum of the van der Waals radii of Cu of 2.80 Å, suggests that strong cuprophilic bonding interaction (d 10 -d 10 ) occurs in B, whereas it is much weaker in the case of A. 70,71 Values of the torsional angles in the [Cu2I4] 2anions are significantly different in the two polymorphs (mean values of 173.86 (4) in A and 162.07(4)° in B), as reported in Table 1.…”

“…3,4,5,6,7,8 Amongst Cu-based compounds, copper(I) iodide derivatives have recently emerged as attractive emissive materials due to their rich optical properties. 9,10,11,12,13 The d 10 electronic configuration of Cu(I) gives rise to diverse coordination number/geometries and associated to the multiple connectivity modes of halides, the family of copper iodides present a great structural diversity, leading consequently to various photophysical properties. Actually, their potential applications as sensors, 14,15,16,17 photocatalytic systems, 18 and emitters in organic light-emitting diodes (OLEDs), 19,20,21,22,23 have been recently reported.…”

Luminescent Thermochromism and White-Light Emission of a 3D [Ag4Br6] Cluster-Based Coordination Framework with Both Adamantane-like Node and Linker

“…Metal halide-based complexes have received great attention owing to their diverse structural characteristics and multiple applicable features in semiconductivity, catalysis, photoluminescence, thermo/photochromism, and so on. − As a branch of these functional materials, the Ag–X (X = Cl, Br, I) system is of particular interest, benefiting from the various coordination geometries of Ag­(I) as well as the flexible linking modes of X – , which endows the structures of the acquired products with a great novelty and originality. Adding their unique physicochemical performance, the Ag–X-based compounds could stand at the forefront of coordination chemistry research. − At present, two types of silver halide hybrids have been reported largely with the assistance of multitudinous organic molecules. With cationic guests such as quaternary ammonium, protonated or alkylated amine, and metal–organic complexes as structure-directing agents (SDAs), numerous haloargentates bearing diverse inorganic skeletons, including discrete clusters and infinite chains, layers, or even complicated networks, could be fabricated.…”

Lattice solvent controlled photochromism of tripyridyl-triazine-based zinc bromide complexes

“…Photochromic systems comprising electron-donating and accepting units have aroused increasing attention, not only because of their potential and practical applications in displays, optical switches, information storage, memory, and other high-tech areas, [1][2][3][4][5] but also because of their photochemical and photophysical properties that could be switched in response to external stimuli. [6][7][8][9][10][11][12] Although a large number of achievements have been made in the fabrication of photochromic systems, the effective modulation of photoinduced intermolecular electron transfer (PIET) accompanying the generation of desirable photochromic properties remains a challenge.…”
