Synthesis of Free‐Standing, Monolayered Organometallic Sheets at the Air/Water Interface

Sheets and rational synthesis are not like fire and water! Hexafunctional terpyridine monomers can be laterally connected by metal salts to result in a mechanically stable, sheetlike entity that can be transferred from the air/water interface to a solid substrate (see the folded, ca. 1.4 nm thin film) and spanned over micrometer-sized holes. This result is considered an important step on the way to 2D polymers.
