Molecular dynamic simulation on the stability of corporated metal organic framework and choline based ionic liquids

A compatibility and stability of Isoreticuiar Metai Organic Framework (IRMOF-1) impregnated witli cigoline based ionic liquids (ILs) are studied by molecular dynamic simulation. Among three proposed IL7IRM0F-1 hybrid composites, cholinium formate, (ChlFm) is nominated as the best IL to be Incorporat...

A compatibility and stability of Isoreticuiar Metai Organic Framework (IRMOF-1) impregnated witli cigoline based ionic liquids (ILs) are studied by molecular dynamic simulation. Among three proposed IL7IRM0F-1 hybrid composites, cholinium formate, (ChlFm) is nominated as the best IL to be Incorporated with IRIVIOF-I since it shows the lowest RMSD value (0.502 nm, 0.637 nm, 0.923 nm) at three lUIRMOF-l w/w ratio (0.4%, 0.8% and 1.2%) respectively and become representative to all three ILs.

The RDF shows that the interaction between Chl+ and Fm- is higher in composite phase compare to bulky phase due to confinement effect of IRMOF-1. Both Chl+ and Fm- seem to be preferred to locate around carboxylate group inside the IRMOF-1 whereby Fm- shows the dominant interaction and strongly interacts with IRMOF-1 compared to Chl+. In terms of mobility, the cation shows high mobility with SDF value of 0.0419 nm2 in which mobility is expected to be increased with increasing of ILs ratio (0.4%, 0.8% and 1.2%) respectively. Intensity of the ions population around IRMOF-1 is interpreted by density map which is in agreement with the RDF analysis. Finally the stability of the IRMOF-1 is confirmed by the radius of gyration (Rg) analysis in which 0.4% ILs shows the most stable conformation with the lowest Rg value = 1.667 nm that is in consistent with the RMSD analysis. Overall, the structural stability of IRMOF-1 is well interpreted and impregnation of ILs literally increase the stability of framework at lower IL/IRMOF-1 w/w ratio.
