What is the effect of ligand flexibility on the formation of coordination polymers and metal-organic frameworks? Investigate the synthesis of MOFs and CPs using different flexible and rigid ligands (such as biphenyl, terphenyl or their derivatives) and determine the properties of these materials such as porosity, surface area, and stability. Compare the results of these experiments and determine the role of ligand flexibility in the formation of CPs and MOFs.
