The International Year of Chemistry 2011… …is an initiative of the International Union of Pure and Applied Chemistry (IUPAC) and the United Nations Educational, Scientific, and Cultural Organization (UNESCO). Under the motto “Chemistry—our life, our future”, it is a worldwide celebration of the achievements of chemistry and its contributions to the well-being of humankind. As part of our own contribution to the International Year of Chemistry, the cover of this special issue features a collage of chemistry from around the world. Going clockwise from the top left-hand corner, the work featured is on amphiphilic lanthanide helicates by Claude Piguet, Emmanuel Terazzi, Jiri Mareda et al. (p. 184); on a multistate switchable [3]rotacatenane by J. Fraser Stoddart et al. (p. 213); on heuristic chemistry—addition reactions by Peter Schreiner et al. (p. 30); on steric, electronic, and secondary effects on the coordination chemistry of ionic phosphine ligands and the catalytic behavior of their metal complexes by Robertus J. M. Klein Gebbink et al. (p. 42); on the synthesis and structural features of 4,5-disubstituted N,N′-di-tert-alkyl imidazolium by Svetlana Polyakova, Ilya M. Lyapkalo et al. (p. 96); on luminescent cyclometalated dialkynylgold(III) complexes of 2-phenylpyridine-type derivatives with readily tunable emission properties by Vivian Wing-Wah Yam et al. (p. 130); on recent developments in methodology for the direct oxyamination of olefins by Timothy J. Donohoe et al. (p. 58); and last but by no means least, on configurational and constitutional information storage by Nobel Prize winner, and co-founder of the journal, Jean-Marie Lehn et al. (p. 248).
