Carbon nanomembranes (CNMs) are two-dimensional (2D) organic materials with a molecular thickness that are synthesized by low-energy electron irradiation of aromatic self-assembled monolayers (SAMs). Using the molecular design, CNMs can be prepared with tunable physical and chemical properties and employed on their own, e.g. as separation membranes or in combination with other 2D materials in hierarchically assembled van-der-Waals heterostructures. Here we present the engineering of photosensitive nanomembranes via post-functionalization of ∼1 nm thick amino-terminated CNMs with azobenzene molecules. We characterize their properties using surface science techniques including X-ray photoelectron spectroscopy (XPS) and compare the obtained characteristics with the azobenzene-based SAMs.
