Triply ferrocene-bridged boroxine cyclophane

Area of Science:

• Supramolecular Chemistry
• Materials Science
• Organometallic Chemistry

Background:

• Covalent organic polyhedra (COPs) are crystalline porous materials with tunable properties.
• Boroxine-based COPs offer a unique platform for constructing novel molecular architectures.
• Ferrocene units introduce redox activity and specific structural motifs.

Purpose of the Study:

• To synthesize and characterize a novel ferrocene-bridged boroxine cyclophane.
• To investigate the formation of minimal covalent organic polyhedra (COPs).
• To explore the structural features of trigonal prismatic COPs.

Main Methods:

• Solvothermal dehydration reaction of 1,1'-ferrocenediboronic acid.
• Single-crystal X-ray diffraction analysis.
• Characterization of the resulting cyclophane structure.

Main Results:

• Successful synthesis of a triply ferrocene-bridged boroxine cyclophane.
• Determination of a rigid, trigonal prism crystal structure.
• Identification of a minimal boroxine-based covalent organic polyhedron (COP).

Conclusions:

• Mild solvothermal conditions are effective for creating complex organometallic cyclophanes.
• The resulting structure represents a new class of minimal COPs with potential applications.
• The trigonal prismatic arrangement highlights the versatility of boroxine chemistry in constructing polyhedra.
