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
