Ligand-Driven Structural Control in Rare Earth-TNDI MOFs

CIF files for two new rare-earth metal-organic frameworks (MOFs), Y-TNDI and Eu-TNDI, synthesized using a rigid tetracarboxylate linker. The dataset, authored by Govu Radha and last updated in May 2026, demonstrates structural diversity with dual molecular building blocks. The Eu-TNDI MOF shows potential for real-time amine detection with nearly 100% quenching efficiency and photochromic behavior.

Use Cases

• Analyzing topological diversity in MOFs based on rare-earth metal and symmetric linker selection.
• Developing mixed-matrix membranes for gas sensing based on the described colorimetric change upon amine exposure.
• Studying photochromic behavior and radical formation in MOFs under visible light.
• Comparing structural characteristics between RE-TNDI and Zr-TNDI MOFs mentioned in the description.

Strengths

• Dataset includes CIF files for two newly reported isostructural MOFs (Y-TNDI and Eu-TNDI).
• The described Eu-TNDI MOF exhibits nearly 100% quenching efficiency for amine detection.
• Structural analysis reveals dual molecular building blocks (8-c hexanuclear cluster and 4-c mononuclear center), challenging prior assumptions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (1.7 MB), potentially limiting the scope of analysis.
