Researchers synthesized novel indium oxide clusters (InOCs) with high nuclearity, including a record [In13] cluster. These clusters exhibit tunable properties and enable self-assembly into diverse extended structures for tailored applications.
Area of Science:
- Inorganic Chemistry
- Materials Science
- Nanotechnology
Background:
- Indium oxide clusters (InOCs) are of interest for their unique properties.
- Controlling the nuclearity and structure of InOCs remains a challenge.
Purpose of the Study:
- To synthesize novel multi-nuclear indium oxide clusters (InOCs) with high nuclearity.
- To explore the structural modification and self-assembly capabilities of these InOCs.
- To investigate the potential for tailoring InOC properties for specific applications.
Main Methods:
- Synthesis of indium oxide clusters using 1,1'-ferrocene dicarboxylic acid (H2FcDCA) as a ligand.
- Characterization of heptanuclear ([In7]) and thirteen-nuclear ([In13]) InOCs.
- Investigating structural modifications through ligand exchange and self-assembly.
Main Results:
- Successfully synthesized cubane-type [In7] and sandwich-type [In13] InOCs, with [In13] being the highest nuclearity reported.
- Achieved adjustable band gaps in [In7] clusters.
- Demonstrated self-assembly of [In7] into Fe-doped dimers ([Fe2In12]) and imidazole-bridged tetramers ([In28]).
- Showcased modification of [In13] clusters with imidazole, methylimidazole, and carboxylic acids to form 1D extended structures.
- Demonstrated ligand substitution with pyrazole, highlighting flexibility in InOC synthesis.
Conclusions:
- The developed method allows for the synthesis of high-nuclearity InOCs with tunable properties.
- The labile coordination sites facilitate structural diversification and self-assembly into extended architectures.
- These findings offer a versatile platform for designing advanced indium-based materials.
