Area of Science:

• Supramolecular Chemistry
• Materials Science
• Organic Chemistry

Background:

• Cyclodextrins are versatile macrocycles with tunable properties.
• Controlling molecular orientation is key to designing advanced materials.
• Hierarchical self-assembly offers pathways to complex architectures.

Purpose of the Study:

• To achieve regioselective di-functionalization of cyclodextrins.
• To direct hydrophobic domains in a geometrically controlled manner.
• To construct a novel hierarchical assembly in the solid state.

Main Methods:

• Regioselective functionalization of cyclodextrin derivatives.
• Characterization of solid-state structures.
• Analysis of host-guest interactions, hydrophobic effects, and hydrogen bonding.

Main Results:

• Successful regioselective di-functionalization of cyclodextrins.
• Demonstration of geometrically controlled hydrophobic domain orientation.
• Formation of a three-level hierarchical assembly driven by multiple non-covalent interactions.
• Creation of a porous organic architecture.

Conclusions:

• Regioselective functionalization is a powerful strategy for controlling molecular assembly.
• Synergistic non-covalent interactions (host-guest, hydrophobic, H-bonding) drive hierarchical structure formation.
• This approach yields novel porous organic architectures with potential applications in materials science.
