The supramolecular attitude of metal-salophen and metal-salen complexes [PDF]

open access: yes, 2018
In this review we cover some aspects of metal-salophen and metal-salen complex chemistry related to their supramolecular attitude. We examined under the lens of the non-covalent interactions their potential to behave as building blocks for auto-assembled
