Rapid determination of the optical and redox properties of a metal–organic framework via in situ solid state spectroelectrochemistry

Abstract

The optical properties of [Zn(2)(NDC)(2)(DPNI)](0/-/2-) (NDC = 2,7-naphthalene dicarboxylate, DPNI = N,N'-di(4-pyridyl)-1,4,5,8-naphthalenetetracarboxydiimide), a redox-active metal-organic framework, have been examined using a simple and robust in situ solid state UV-Vis-NIR spectroelectrochemical technique.

Facile Deposition of Multicolored Electrochromic Metal–Organic Framework Thin Films

“…[23,24] Furthermore, core substitution of NDIs with electron donor groups results in the appearance of charge-transfer transitions in the visible spectrum, affording color-tunable and sometimes fluorescent dyes with applications in optoelectronics and sensing. [37,44] Here, we show that processing them as homogeneously dispersed thin films enables their use as multicolored electrochromic devices. [42,43] However, studies of their electrochemical properties remain scarce.…”

DFT study on the tautomerism of organic linker 1H-imidazole-4,5-tetrazole (HIT)

“…Redox potential is an important tool to understand the electron accepting or donating character of a molecule [76][77][78][79]. Here, the understanding of the influence of tautomerism on the redox nature of the HIT molecule will be useful for metal coordination.…”

Facile redox state manipulation in Cu(i) frameworks by utilisation of the redox-active tris(4-(pyridin-4-yl)phenyl)amine ligand

“…[35] The cell consisted of a Pt wire counter electrode and a Ag/Ag + quasi-reference electrode. UV/Vis/NIR spectroscopy was performed on a Cary 5000 Spectrophotometer equipped with a Harrick Praying Mantis accessory, where dried BaSO 4 was used for the baseline.…”
