Electron irradiation of aromatic self-assembled monolayers results in their conversion into a novel 2D carbon material  Carbon Nanomembranes (CNMs)  molecular nanosheets with a thickness of ~ 1 nm[1]. Similar to graphene or other atomically thin 2D materials (hBN, MoS2, etc.) CNMs possess mechanical integrity and therefore can be transferred from their original substrates onto new substrates, fabricated as suspended sheets or stacked into van der Waals heterostructures with the precise control over their thickness. Their physical and chemical properties can be tuned via an appropriate choice of molecular precursors or their post modification, providing a flexible platform for engineering of functional 2D materials. In this talk, some examples of these materials and their device applications will be presented. These examples include: (i) biofunctional and photoactive CNMs [2]; (ii) growth of graphene with adjusted electronic and structural properties [3-4]; (iii) chemical functionalization of graphene and MoS2 field-effect devices [5]; (iv) nanolithography of free-standing atomically thin sheets [6]; (v) novel hybrid 0D/2D layered materials [7].
