Summary
Researchers modified a porous molecular network using hydrogen bonds. This created a new cluster on a graphite surface, capable of forming ordered 2D structures with guest molecules.
Area of Science:
- Supramolecular chemistry
- Surface science
- Materials science
Background:
- Porous molecular networks offer tunable properties for advanced applications.
- Hydrogen bonding is a key interaction for self-assembly of molecular structures.
- Surface-confined self-assembly allows for precise control over material organization.
Purpose of the Study:
- To demonstrate the derivatization of a porous molecular network via hydrogen bonding.
- To investigate the formation of heteromolecular clusters on a surface.
- To explore the potential for creating ordered 2D structures with guest molecules.
Main Methods:
- Utilizing scanning tunneling microscopy (STM) for surface analysis.
- Employing hydrogen bond interactions for molecular network modification.
- Forming heteromolecular clusters on highly oriented pyrolytic graphite (HOPG) surfaces.
Main Results:
- Formation of a heteromolecular cluster (TCDB6-Bpy6) from 1,3,5-tris (10-carboxydecyloxy) benzene (TCDB) and 4,4'-bipyridyl (Bpy).
- Observation of the cluster formation on HOPG under ambient conditions.
- Demonstration of the derivatized network's ability to incorporate guest molecules like coronene into well-ordered ternary 2D structures.
Conclusions:
- Hydrogen bond derivatization is an effective strategy for modifying porous molecular networks.
- Surface-confined self-assembly can lead to the formation of complex heteromolecular structures.
- The resulting 2D structures show potential for accommodating guest species in an ordered manner.

01:04Hydrogen Bonds
A hydrogen bond is formed when a weakly positive hydrogen atom already bonded to one electronegative atom (for example, the oxygen in the water molecule) is attracted to another electronegative atom from another polar molecule, such as water (H2O), hydrogen fluoride (HF), or ammonia (NH3). The huge electronegativity difference between the H atom (2.1) and the atom to which it is bonded (4.0 for an F atom, 3.5 for an O atom, or 3.0 for an N atom), combined with the very small size of an H atom...
00:54Radical Formation: Homolysis
A bond is formed between two atoms by sharing two electrons. When this bond is broken by supplying sufficient energy, either two electrons can be taken up by one atom forming ions by the cleavage called heterolysis, or the two electrons are shared by two atoms, with one each creating radicals by the cleavage called homolysis.
02:17Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
Catalytic hydrogenation of alkenes is a transition-metal catalyzed reduction of the double bond using molecular hydrogen to give alkanes. The mode of hydrogen addition follows syn stereochemistry.
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

01:20Aldehydes and Ketones with Water: Hydrate Formation
An oxygen-based nucleophile, like water, can undergo addition reactions with aldehydes and ketones. The reaction leads to the formation of hydrates, also referred to as 1,1-diols or geminal diols.
The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...

01:15Hydrolysis
Overview
Hydrolysis is a chemical reaction in which the addition of water breaks down a polymer into its simpler monomer units. For example, peptides break into amino acids, carbohydrates into simple sugars, and DNA into nucleotides. Enzymes often facilitate these processes.
Hydrolysis Reverses Dehydration Synthesis
Complex carbohydrates can be broken down by breaking the bonds between individual sugar units. The reaction breaks a glycosidic bond as water is added to the compound. The...

01:17Radical Chain-Growth Polymerization: Chain Branching
The skeletal structure of polymers synthesized via radical polymerization is always branched. For example, the polymerization of ethylene by radical polymerization results in a low-density grade of polyethylene with a heavily branched skeletal structure. Here, the radical site abstracts hydrogen from the growing chain, and the radical site shifts from the end (a primary carbon center) to anywhere within the growing chain (a secondary carbon center). Consequently, the part of the chain from the...
