Arias, Mauricio; Concepción, Javier; Crivelli Picco, Irma; Delgadillo, Alvaro; Díaz, Ramiro; Francois, Angélica; Gajardo, Francisco; López, Rosa; Leiva, Ana María; Loeb, Bárbara (ELSEVIER, 2006-07-11)Different strategies to improve the excited state properties of polypyridinic complexes by varying ligand structure and molecular geometry are described. Bidentate and tetradentate ligands based on fragments as ...
