Summary: We have established protocols for funcionlizar properly synthesis of trisbipiridina ruthenium complex and different molecules, potential aceptores electron (viólogenos and fulerenos), as well as diadas with groups fosfónicos allowing its inclusion in inorganic matrices of gamma-ZrP. Most acids fosfónicos thus obtained, even some fulerenos, have joined successfully to the matrix and inorganic materials synthesized have been characterized by the usual technical positively in this work (elemental analysis, solid-state NMR and dissolution, lightning X dust, thermogravimetry, etc..). We have synthesized three types of materials with different properties fotofísicas: giving electrons, aceptores and showing transfer cargo fotoinducida. - Materials giving electrons: have synthesized phases with different proportions of ruthenium complexes in the interior, either through inercalación or exchange, without prior insertion of the amines or alcohols in the gamma-ZrP. Fotofísicas and electrochemical properties of the complex were not affected once incorporated within the inorganic matrix. - Materials aceptores electron: for the first time, have prepared solid organo-inorgánicos derivatives of diquat or fulerenos. Levels of exchange obtained with the latter are high given the polarity and the difficulty of inserting these organic molecules. - Materials with charge transfer fotoinducida. It has achieved its goal of separating loads within the walls inorganic. The demise of the luminescence of the complex of ruthenium, is present when the acceptor, demonstrates unequivocally. The effectiveness of the process is greater the higher the mobility of viológenos incorporated. Or where the complex is located in the gaps created by fulerenos previously interspersed. The objeticvos made open a very interesting picture of the future in which determine, among other details, the half-life of the separation of charges on the basis of peer dador-acpetor who intend to study, as well as the applicability of the materials prepared in solar cells.
