Engineering Contradiction Analysis
1Reliability
If conventional MILs are used, then magnetic susceptibility is achieved, but viscosity becomes excessively high
Solution Approach 1:
The patent changes the chemical structure parameters of MILs by incorporating DGE ligands with specific aromatic and aliphatic alkyl substituents, and pairing them with paramagnetic metal centers, to achieve ultra-low viscosity while maintaining high magnetic susceptibility
Solution Approach 2:
The patent creates composite MIL structures combining organic DGE ligands with inorganic paramagnetic metal centers, achieving a synergistic effect where the organic component provides low viscosity and the inorganic component provides high magnetic susceptibility
2Force
If MILs are diluted with traditional solvents to reduce viscosity, then viscosity decreases, but unique physicochemical properties are lost
Solution Approach 1:
The patent modifies the intrinsic parameters of MILs by selecting specific DGE ligands and paramagnetic metal combinations that naturally produce ultra-low viscosity without requiring dilution, thereby preserving all unique physicochemical properties
3Force
If anions with hfacac and NTf2 are used, then viscosity is reduced, but magnetic susceptibility is insufficient
Solution Approach 1:
The patent combines organic DGE ligands with inorganic paramagnetic metal centers to create composite anions that simultaneously provide low viscosity (from the organic ligand structure) and high magnetic susceptibility (from the paramagnetic metal centers)
Solution Approach 2:
The patent changes the compositional parameters of the anion by incorporating specific paramagnetic metal centers into the DGE ligand framework, achieving dual optimization of viscosity and magnetic susceptibility
