From 1D coordination polymers to Metal Organic Frameworks by the use of 2-pyridyl oximes.

The synthesis and characterization of coordination polymers and metal-organic frameworks (MOFs) has attracted a significant interest over the last decades due to their fascinating physical properties, as well as their use in a wide range of technological, environmental, and biomedical applications....
