This paper is a review concerning metallic derivatives linked to the surface of phosphorus-containing dendrimers, that are dendrimers possessing one phosphorus at each branching point. The synthetic aspects will be described first, concerning in particular the complexation of transition metals (Fe, W, Rh, Pt, Pd, Ru) by monophosphine or diphosphine end groups, the grafting of metallocene derivatives (zirconocene and ferrocene), and the interaction with various clusters (Au-Fe, Au, Ti). Some applications of these metallo phosphorus dendrimers will be described in the field of materials science (modification of the surface of existing materials or creation of new materials), and in the field of catalysis (Stille couplings, Knoevenagel condensations, Michael additions).
