Special Issue Information

Dear Colleagues,

I would like to start the presentation to this Special Issue by remembering the beginning of metal sandwich chemistry: the discovery of ferrocene. The chronicle of its discovery has been repeated over and over, and has evolved into a tale, culminating in the Nobel Prize. Ferrocene immediately received an enormous amount of attention and soon became an iconic molecule, perhaps the symbol of organometallic chemistry, being a combination of intrinsic beauty and unique properties. This curiosity-driven discovery opened an amazing field of research, which led to new chemical discoveries with their own applications.

Indeed, in 1972, on the wave of ferrocene’s discovery, Salzer and Werner isolated the first tripledecker cation, [Ni2(C5H5)3]+, and, subsequently, Grimes presented the first crystallographically characterized triple-decker complex, [(C5H5Co)2RC2B3H4] (R = Me/H), opening a new, exciting age for organometallic chemistry: the area of multidecker sandwich complexes.  Numerous homo- or hetero- multidecker complexes were prepared involving a plethora of molecular entities, such as heterocycles, arenes, porphyrins, phthalocyanines, carborane cages, and so on, which may act as bridging or capping ligands. The broad potential applications of these complexes, derived from the enormous possible combinations of ligands and metals, range from electronic, magnetic, and optical materials to molecular information storage applications. To celebrate 50 years from the thrilling discovery of tripledeckers, Inorganics is glad to announce the publishing of a Special Issue about multidecker compounds.

I am pleased to invite you to contribute to this Special Issue with research and/or review articles, dedicated to recent advances in the wide-ranging organometallic chemistry of multidecker compounds, with a special focus on electrochemical aspects. In the editors’ intentions, this issue will also be a source of inspiration for synthetic-, theoretical-, and electro-chemists and to serve as a springboard for future developments (and applications) in the area of multidecker compounds. This Special Issue also aims to reinvigorate the innate curiosity of those acquainted with basic research.
