Supramolecular Chemistry of Titanium Oxide Clusters

Area of Science:

• Inorganic Chemistry
• Supramolecular Chemistry
• Materials Science

Background:

• Titanium oxide clusters (TOCs) are emerging as key inorganic molecular entities.
• Their unique structures and functionalities are crucial for supramolecular chemistry.
• Research over the past three decades has established their significance.

Purpose of the Study:

• To provide a comprehensive perspective on the structures and functionalities of TOCs.
• To demonstrate the paramount roles of TOCs in supramolecular chemistry.
• To review four types of supramolecular assemblies based on TOCs.

Main Methods:

• Review of literature on TOCs over the past three decades.
• Analysis of structural properties and functionalities of TOCs.
• Discussion of four types of supramolecular assemblies: ion inclusion hosts, mechanically interlocked molecular systems, surface site reactivity, and hierarchical structures.

Main Results:

• TOCs serve as effective hosts for ion inclusion.
• Cyclic TOCs are building blocks for mechanically interlocked molecular systems.
• Surface sites of TOCs exhibit reactivity toward ligand exchange.
• TOCs form complex hierarchical structures.

Conclusions:

• TOCs possess diverse functionalities applicable in supramolecular chemistry.
• Further design and synthesis of functional TOC-based systems are anticipated.
• This research will advance supramolecular and coordination chemistry of titanium.
