A coordination polymer of copper(i) iodide with 654 topology constructed from Cu4I4(DABCO)4

Stimuli-responsive Luminescent Copper(I) Complexes for Intelligent Emissive Devices

“…58 The crystal structure of 7, determined by Bi et al, exhibited unit cell porosity of about 20%, enabling the adsorption of small solvent vapor molecules. 59 In the presence of methanol or acetonitrile vapor, the structural transformation of the orthorhombic phase 7o to the tetragonal phase 7t occurred, maintaining the cubane-type core structure ( Figure 5). Concomitantly, the emission band assignable to the 3 CC phosphorescence blueshifted from 580 to 556 nm.…”

Design and construction of self-penetrating coordination frameworks

“…Notably, different 4-connected self-penetrating frameworks may be observed in a pair of isomers for [Cu 4 I 4 (dabco) 2 ]-α (22) [32] and [Cu 4 I 4 (dabco) 2 ]-β (23) [33] (dabco = 1,4-diazabicyclo[2.2.2]octane). Both structures are constructed from the Cu 4 I 4 (dabco) 4 supertetrahedron units (Fig.…”

Reversible Interconversion between Luminescent Isomeric Metal–Organic Frameworks of [Cu4I4(DABCO)2] (DABCO=1,4‐Diazabicyclo[2.2.2]octane)

“…[26,27] In this paper we investigate the interconversion between two MOFs obtained from the combination of the inorganic cluster Cu 4 I 4 with the organic bifunctional ligand 1,4-diazabicycloA C H T U N G T R E N N U N G [2. 2 ] form I is obtained by reaction of DABCO and CuI in aqueous solution or by solvothermal reaction as described by Bi et al, [7] while form II is obtained by reacting DABCO and CuI in acetonitrile. Both MOFs exhibit a high degree of porosity and large open channels, which are promising for gas storage.…”

“…[2][3][4] Although copper(I) iodide and bidentate ligands have been employed in the preparation of metal-organic framework (MOF) compounds, those containing cubane-like clusters are less common. [5][6][7][8][9][10][11][12][13][14][15] Moreover, iodide clusters of Cu I show unique luminescence properties that have been the subject of great interest over the last 40 years, [16][17][18][19][20] and have been associated with attractive Cu···Cu (cuprophilic) interactions. [21,22] We have long been interested in the preparation of metal-organic as well as hybrid organic-inorganic framework compounds [23][24][25] within the scope of our crystal engineering endeavours.…”
