Since the discovery of #graphene, extensive studies have revealed various types of novel two-dimensional #polymers such as transition metal dichalcogenides, covalent organic frameworks, and carbon allotropes. *
Coordination #nanosheets (CONASHs) are bottom-up-type, two-dimensional polymers woven through coordination reactions of molecular, ionic, or atomic components. *
Due to the diversity of their chemical and physical properties arising from an infinite variety of ligand and metal ions, CONASHs have attracted considerable attention. Functional CONASHs tethering 1,2-dithiolate and its analogues, carboxylate, dipyrromethine, and polypyridyl ligands have been developed. *
In the article “A Bis(terpyridine)nickel(II)-Based Coordination Nanosheet: A Redox-Active Material with Flexibility and Transparency” Kenji Takada, Hiroaki Maeda and Hiroshi Nishihara report a novel functional bis(terpyridine)metal(II) complex coordination #nanosheet (CONASH) comprising a three-armed terpyridine ligand and Ni2+ ion. *
The colourless Ni-terpyridine CONASH was synthesized by the method of interfacial coordination reaction at an interface of two immiscible liquids. *
The synthesized CONASH was characterized with various microscopic observations such as TEM, SEM, and #AFM, and spectroscopic measurements such as XPS, IR, SEM/EDS, and UV–Vis spectroscopy. *
The bis(terpyridine)nickel(II) complex nanosheet demonstrated redox-activity stemming from terpyridine complexes without distinctive colour change. Thus, the bis(terpyridine)nickel(II) coordination nanosheet is a potential redox-active material with colourlessness and flexibility, necessary for future #transparentelectronics.*
