“…Hierarchical assembly is common in biological systems and biomaterials. − Hierarchically formed architectures typically exhibit tunable periodicity, structural complexity, and have attracted great attention for both fundamental understanding of assembly process and potential application in molecular electronics and molecular devices. − 2D molecular self-assembly on solid–gas − or solid–liquid interfaces − is an important model system for understanding the hierarchical assembly process. In a typical hierarchical assembly structure, the molecules can assemble into elemental building units or molecular clusters through primary intermolecular interactions, which then further assemble into more complicated hierarchical structures .…”

The hierarchical organization of building blocks is an important characteristic of self-assembly. Herein, we report a series of triangular hierarchical assemblies formed by C 3 -symmetric 5,10,15-triethyl-10,15-dihydro-5H-diindolo[3,2a:3′,2′-c]carbazole-2,7,12-tricarbaldehyde (M1) on the graphite surface. The molecule assembles into a hexagonal array on the graphite surface at room temperature with a trimeric assembly motif as the basic building block of the hierarchical assembly. With the increase of annealing temperature, the sizes of triangles in hierarchical assemblies vary from large to small with the presence of antiparallelly arranged molecular dimers as building blocks at the triangular boundaries. The hierarchical-order-level-dependent intermolecular interaction and molecule−substrate interaction were modeled, and the entropy contributions of alkyl substitution at different temperatures were proposed to account for the observed structural evolution process. This work provides a new example of hierarchical assembly directed by temperature and is beneficial for the understanding of both the assembling process and the underlying kinetics and thermodynamics for hierarchical molecular nanostructures.

H-Benzo[cd]pyrene ('Olympicene') is a polyaromatic hydrocarbon and non-Kekulé fragment of graphene. A new synthetic method has been developed for the formation of 6H-benzo[cd]pyrene and related ketones including the first time isolation of the unstable alcohol 6H-benzo[cd]pyren-6-ol. Molecular imaging of the reaction products with scanning tunnelling microscopy (STM) and non-contact atomic force microscopy (NC-AFM) characterised the 6H-benzo[cd]pyrene as well as the previously intangible and significantly less stable 5H-benzo[cd]pyrene, the fully conjugated benzo[cd]pyrenyl radical and the ketones as oxidation products.
