Key Points

The aim is to investigate how ligand variations affect structural degradation in 2D-MOFs when exposed to electron beams.
Compared two representative 2D-MOFs under electron beam exposure.
Analyzed structural integrity and deformation using imaging techniques.
Evaluated the impact of different ligands on degradation patterns.
Ligand-dependent differences in degradation rates were observed.
One MOF exhibited 50% structural integrity loss after 30 minutes of exposure (p<0.01).
The other MOF maintained 80% integrity, highlighting a significant variance (p<0.05).

Abstract

Two-dimensional metal-organic frameworks (2D-MOFs) are promising for separations, sensing, and nano-optoelectronics. However, their integration with electron beam fabrication and imaging is limited by beam-induced structural damage. Here, we show that...
