Summary: The self-assembly process of a BODIPY derivative functionalized with uracil groups was thoroughly investigated using STM and DFT methods. The formation of hydrogen bonds between uracil groups was identified as the key factor contributing to the construction of ordered self-assembly structure. Additionally, the nanotribological property of the self-assembly on HOPG surface was measured using AFM.

Summary: Intermolecular interactions play a crucial role in guiding self-assembly on surfaces. Precise control over these interactions by rational design of the molecule allows fine control over the self-assembly patterns. Hydrogen bonding significantly impacts two-dimensional molecular self-assembly and can be a potent strategy to modulate molecular 2D lattices on surfaces.

Summary: Currently, there is limited research on the self-assembly of three-dimensional molecules on surfaces. These molecules have a greater variability in their modes of adsorption compared to (nearly) planar molecules. This variability can significantly affect the expression of intermolecular binding motifs and the formation of supramolecular structures. The study found that molecule-surface interactions can be tuned to facilitate crystal engineering in two dimensions.

Summary: In this study, the effect of concentration on the self-assembled molecular network formation process was investigated using scanning tunneling microscopy. Isophthalic acids were chosen as a model system, and the adsorption behavior was evaluated at the nanoscale. The results showed the existence of a critical concentration for self-assembly, with the molecular structure having a significant impact on this threshold value. Furthermore, highly cooperative behavior was observed at the liquid/solid interface, providing a rare example of quantitative measurement of cooperative phenomena.

Summary: This study investigates the trapping of coronene and zinc phthalocyanine molecules by a two-dimensional self-assembled nanoarchitecture using scanning tunneling microscopy at the liquid-solid interface. The results show that coronene molecules only occupy a small fraction of the cavities, while zinc phthalocyanine molecules occupy a majority of the cavities and fill them completely in a short period of time.

Summary: This study presents the first real space characterization of borazine molecules and their self-assemblies on solid supports. The adsorption of borazine on Ag(111) surface is weak and non-dissociative, with the ring aligned parallel to the surface plane. Borazine molecules prefer hollow adsorption sites, leading to the assembly of both porous and dense-packed structures. STM-based manipulation is demonstrated to modify the borazine adsorption configuration.

Summary: This study investigates the self-assembled behavior of an unsymmetric molecule (BCDTDA) and the regulatory behaviors of COR and three bipyridine derivatives on BCDTDA self-assembly structures. STM is used to observe the variation of assembled behaviors at the solid-liquid interface. The concentration effect leads to the formation of hydrogen bonded dimers, and the regulatory molecules either maintain or destroy the dimeric structure of BCDTDA, forming different co-assembled structures. The discovery of molecular interactions provides a promising strategy for the construction of functional nanostructures and devices.

Summary: In this study, a graph neural network was used to predict the self-assembly of functional polycyclic aromatic hydrocarbons (PAHs) on metal surfaces. Experimental data from scanning tunneling microscopy (STM) were used to train the model. Compared to traditional machine learning algorithms, our model exhibited better predictive performance. The generalization of the model was further verified by comparing the predictions with experimental results of different functionalized molecules. Our results demonstrate the possibility of using trained experimental data sets to predict and design nanostructures with functional molecules.

Summary: The self-assembled material stabilized by halogen bonding, m-BrTBE, forms uniform ball-like aggregates with high photoluminescence quantum yield, showing a more red-shifted emission compared to TBE. The enhanced AIE behavior is attributed to the important effect of meta-bromide substituents, promoting radiative processes and blocking nonradiative relaxation pathways.

Summary: Fabricating tetraphenylethylene (TPE)-functionalized metal-organic frameworks (MOFs) on surfaces and understanding the growth mechanism were investigated. TPE molecules formed self-assembled patterns on Au(111) surface at 298 K. Stepwise annealing led to the formation of surface-stabilized radicals and metal-organic networks. By replacing the substrate with Cu(111), more ordered MOFs were obtained due to the higher catalytic activity.

Summary: In order to obtain dendrite-free zinc-ion batteries, a theoretically guided Zn2+ confining-anchoring strategy is proposed based on the different strengths between the alpha-cyclodextrin (& alpha;-CD) additive and various crystallographic planes of zinc. The strategy enables the preferential growth of Zn2+ ions along the (002) plane of zinc, suppressing dendrite growth and improving battery performance. With alpha-CD additives, the zinc anode exhibits exceptional cumulative capacity and high coulombic efficiency, demonstrating its potential for practical applications.

Summary: Shape persistent macrocycles (SPMs) consisting of a π-conjugated backbone and flexible side chains have shown promising potential in generating interesting self-assembly nanopatterns and acting as templates to trap guest molecules on a 2D surface. In this study, an oval six-membered macrocycle (M1) with specific linkers was designed and synthesized. The self-assembly behavior and interaction with guest molecules on a graphite surface were investigated using scanning tunneling microscopy (STM). The results showed that M1 molecules formed three ordered macrocyclic patterns which selectively trapped triphenylene (Tp) and pyrene (Py) molecules. Molecular mechanics (MM) simulations were also utilized to further understand the formation mechanism and adsorption stability of the host-guest nanopatterns on the graphite surface.
