CAU-1

CAU-1 is an aluminum-based metal organic framework synthesized using 2-aminobenzene-1,4-dicarboxylic acid as the organic linker. The structure exhibits a highly porous architecture with large cage-like cavities and excellent chemical stability. The material demonstrates strong adsorption properties and high surface area, making it suitable for various advanced applications in gas separation, carbon capture, catalysis, and drug delivery systems. CAU-1 typically appears as a yellow crystalline powder with particle sizes ranging from 1–5 µm.

Frequently asked questions

Quick answers about CAU-1. Can't find yours? Contact us

How do I activate CAU-1?

Commonly by exchanging the solvent with methanol and then heating under vacuum at around 150 °C for several hours. Use the conditions on the TDS for exact values.

Why does CAU-1 have amino groups, and why does that matter?

Its linker carries –NH₂ groups. They increase the affinity for CO₂ and allow post-synthetic modification, which is why CAU-1 is used in CO₂ adsorption and catalysis research.

What is CAU-1 typically used for?

CO₂ adsorption and separation, catalysis, post-synthetic functionalisation studies, and applications where an aluminium-based, low-toxicity MOF is preferred.

Can I order CAU-1 in larger quantities?
