From layer sliding to near-zero compressibility: novel high-pressure flexibility and CO₂ site evolution in pre-ELM-11 and ELM-11

Key Points

• The aim is to understand how mechanical stress affects the flexibility and CO₂ site evolution in metal-organic frameworks (MOFs).
• Comparison of high-pressure flexibility between ELM-11 and pre-ELM-11 MOFs.
• Analysis focused on mechanical stress responses and CO₂ sorption capabilities.
• ELM-11 exhibits enhanced flexibility under high pressure compared to pre-ELM-11.
• Significant changes in CO₂ adsorption sites were observed with applied mechanical stress.
