About this collection
Welcome to the themed issue on Molecular metal-containing soft materials. This collection is focused on emerging trends related to metallosurfactants, metallomesogens, metallopolymers, metallorganic frameworks, supramolecular, and hierarchical materials that take advantage of the geometric, redox, and magnetic properties of 3d, 4d, 5d transition metals, lanthanides, and main group metals to build up organized and often responsive architectures based on “soft” organic scaffolds.
It is Guest Edited by Claudio Verani (Wayne State University) and Richard Layfield (University of Sussex).
