• Presentation of functional and structural models based on calixarenes.
• Discussion of non-covalent interactions (e.g., hydrogen bonding) in synthetic systems.

Main Results:

• Calixarenes serve as effective biomimetic catalysts.
• Preorganization of catalytic groups by calixarenes enhances substrate binding.
• Dynamic binding leads to fast turnover and product release.

Conclusions:
