Coordination Polymers (CPs) are periodic architectures defined by the assembly of metal entities and ligands through coordination bonds. They can be designed to present porous architectures, known as Metal-Organic Frameworks (MOFs). They can be prepared as bulk materials and at the nanoscale using bottom-up synthesis or top-down approaches.
