With this project we are synthesizing a new series of organometallic dendrimers from generation 0 to 2, based on derivatives of 2,4,6-trisubstituida-1 ,3,5-triazine with fragments of organometallic platinum etenilruténio and inserted in the main chain with a view to their possible use as nonlinear optical materials. The dendrimers with terminal groups are functionalized acetylide fragments complexes: M (PP) 2CI (M = Ru; PP = dmpe (1,2-bis (ethane dimetilfosfino), M = Pt, PP = PEt3) etenilferrocenil ruthenium (II ) or platinum (II), known good electron donors. In preparation of this family of dendrimers will apply a combination of synthesis strategy for engagement with the method of divergent synthesis of dendrimers.

The characterization of the new family of compounds will be done using chromatographic and spectroscopic techniques chains. The redox behavior of metal centers in dendrimers is studied by cyclic voltammetry and coulometry.
