Starting very early, with the findings of Zeise, or Pope and Peachey, organoplatinum complexes were studied intensely in the 1970s and 1980s and were found to be quite stable and very versatile. From then on, the number of publications on organoplatinum complexes has more than doubled in each subsequent decade, and organoplatinum complexes have stretched into many fields of application today. This introduction to the Special Issue on "Organoplatinum Complexes" spans from the history of organoplatinum complexes to the seven manuscripts published in the frame of this Special Issue, representing some of these fields. Some say that the 1970s and 1980s of the last century were dull and boring. This might possibly be true for pop music or arts but surely not appropriate for organoplatinum complexes. Those were the days when organoplatinum chemistry received a real boost. Scientific giants, such as Joseph Chatt, F.
