π-Conjugated Nickel Bis(dithiolene) Complex Nanosheet


Hiroshi Nishihara

A π-conjugated nanosheet comprising planar nickel bis(dithiolene) complexes was synthesized by the reaction on water surface using a liquid−liquid interfacial reaction using benzenehexathiol in the organic phase and nickel(II) acetate in the aqueous phase. It produced a semiconducting bulk material with a thickness of several micrometers.   Atomic force microscopy and scanning tunneling microscopy confirmed that the π-conjugated nanosheet was single-layered. Modulation of the oxidation state of the nanosheet was possible using chemical redox reactions.
