The coordination nanosheet (CONASH)

•Two-dimensional polymer based on coordination compounds, abbreviated as CONASH.•CONASH fabricated by means of dry processes, such as organic molecular beam epitaxy and electron beam heating evaporation.•CONASH by means of wet processes, such as liquid/liquid and gas/liquid interfacial reactions.•Potential applications of CONASH in nanomaterials science.

This review presents recent progress relating to metal-complex two-dimensional polymers, coordination nanosheets (CONASHs), an emerging class of material. Section 2 summarizes CONASHs fabricated by dry processes, such as organic molecular beam epitaxy and electron beam heating evaporation under ultra-high vacuum conditions. Section 3 describes CONASHs fabricated by wet processes, such as liquid/liquid and gas/liquid interfacial reactions. Section 4 describes the potential applications of CONASHs in nanomaterial science.
