Two Hybrid Polymeric Iodoargentates Incorporating Aromatic N-Heterocycle Derivatives as Electron Acceptors

Two new hybrid polymeric iodoargentates, [Ag₂I₂(phen)]_n (1; phen = 1,10-phenanthroline) and [AgI(bpt)]_n (2; bpt = 3,5-bis(pyrazinyl)-1,2,4-triazole), were prepared by the hydrothermal methods. 1 displays a new type of taenioid, [Ag₂I₂(phen)]_n, chain incorporating phen molecules, while 2 exhibits a unique 2D hybrid iodoargentate based on a combination of the [AgI]_n layer and bpt molecules as electron acceptors. Such a 2D layer is the first example of an inorganic iodoargentate layer covalently bonding to aromatic N-heterocycle derivatives within the iodoargentates. 1 and 2 exhibit photocurrent response properties.

Strongly emissive white-light-emitting silver iodide based inorganic–organic hybrid structures with comparable quantum efficiency to commercial phosphors

A series of one-dimensional silver iodide based inorganic–organic hybrid structures with tunable white light emissions and high quantum efficiency have been synthesized by Cu substitution.

Two Silver Coordination Network Compounds with Colorful Photoluminescence

The excitation-wavelength-dependent photoluminescence (EWDP) property of flexible organic ligand 1,4-bis(2-methyl-imidazol-1-yl)butane (Bmib) was observed. Herein, Bmib was chosen as a bridge linker to react with AgX (X = Br and I) to synthesize novel coordination network compounds (CNCs) with interesting EWDP properties. As anticipated, under the same hydrothermal synthesis conditions, two new isomorphic CNCs, i.e. [Ag2(Bmib)Br2]∞ (IAM16-1) and [Ag2(Bmib)I2]∞ (IAM16-2), as the first examples of CNCs showing EWDP properties, have been obtained. The EWDP properties may be attributed to the stretch and rotation of the long -(CH2)4- chains of Bmib and the spatial orientation adjustment of the methyl group of each imidazole ring at different excitation wavelengths. It is a great challenge to point out the emission mechanisms of CNCs merely from the experimental results due to their multiple charge transfer routes. To address this issue, we adopt DFT calculations to pursue in-depth investigation of the emission mechanisms for IAM16-1 and IAM16-2, respectively.
