Spotless catalysts : Ligand immobilization was studied by two‐photon fluorescence microscopy with a fluorescent nixantphos ligand as probe (see picture). In the immobilization process ligand aggregates form in solution and are deposited on the support, where they appear as bright spots in fluorescence images. Preventing their formation leads to “spotless” catalysts with superior catalytic properties.
