Specific Bifunctionalization on the Surface of Phosphorus Dendrimers Syntheses and Properties

Dendrimers are highly branched macromolecules possessing, in most cases, identical terminal functions. However, it is sometimes desirable to have two types of surface functions order fulfil specific properties. The stochastic functionalization frequently used for such purposes, but the presence an uncontrolled number each type function, albeit acceptable research has no practical use. Thus, find strategies suitable precise grafting different functional groups on dendrimers. easiest way, and widely used, consists using a bifunctional monomer be grafted all Two other known rarely used: modification existing generate functions, sequential one function then second function. three methods illustrated this review with polyphosphorhydrazone (PPH) dendrimers, together their properties as catalysts, materials, biological tools.
