About this collection

Guest edited by Professor Mike Ward, Editor-in-Chief, University of Warwick, UK

The chemistry of the f-block elements is a microcosm of modern chemistry as a whole. From being a relatively under explored-section of the periodic table last century when transition-metal organometallic and then metallo-suprmolecular chemistry were huge growth areas, the f-block elements have caught up because of the remarkable combination of useful properties that they provide. The lanthanides alone make a substantial contribution to leading developments in areas as diverse as single-molecule magnetism, medical imaging and homogeneous and heterogeneous catalysis; and their luminescence properties alone are exploited for applications in cell imaging, optical communications, sensing and analysis, and efficient lighting.  Actinide chemistry is of course dominated by issues related to nuclear fuel processing, and analytical methods associated with detection of radionuclides in the environment. In this collection of 50 articles published in RSC Advances from 2015 you will find a cross section of current developments in f-block chemistry that are helping to define the state-of-the-art, and I hope you enjoy browsing through them.
