<div><b>Abstract</b><br></div><div>In this paper, we report a simple approach to study the fundamental aspect of light-responsive metal organic framework (MOF) in UiO-66 topology through a mixed-ligand approach. Apart from change in the structural property, the loading of azobenzene linker inside the framework also affects the CO<sub>2</sub> light-responsive property and CO<sub>2</sub>/N<sub>2</sub> selectivity which could help to design future low-energy CO<sub>2</sub> adsorbents. Further study to incorporate the MOFs into mixed matrix membranes also indicates the benefit of higher azobenzene loading in the MOF to enhance the CO2/N2 separation performance since it can improve the separation performance which could not be obtained in non-functionalized fillers.</div><div><br></div><div><b>Data Repository</b></div><div>Research data and additional high-resolution images are available from the open repository: https://doi.org/10.5281/zenodo.2533852</div>
