N2 - The synthesis of a new family of phosphorus dendrimers is described up to the fifth generation (96 end-groups). The reaction is based on the nucleophilic substitution of P(S)Cl2 end-groups by 4-hydroxy-3- methoxycinnarnaldehyde, and by the condensation of CHO end-groups with a dichlorophosphorhydrazide. The structure of the first generation has been determined by X-ray diffraction. This structure shows that the OC 6H3CH=CHCH=NNMeP(S) linkage is close to planarity, which indicates an extended conjugation of this linkage that leads to a semi-rigid skeleton for these dendrimers.
