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 ...

Gajardo, Francisco; Barrera, Mauricio; Vargas, Ricardo; Crivelli Picco, Irma; Loeb, Barbara (American Chemical Society, 2011-05-31)When tested in solar cells, ruthenium polypyridinic dyes with extended π systems show an enhanced lightharvesting capacity that is not necessarily reflected by a high (collected electrons)/(absorbed photons) ratio. ...

Zúñiga, César; Crivelli Picco, Irma; Loeb, Bárbara (Elsevier, 2015)In this work we report the preparation of six new donor–metal–acceptor (D–M–A) type complexes of ruthenium(II) with the highly absorbing ‘‘chromophoric’’ ligand 4,40-bis(2-(4-methoxyphenyl)styryl)- 2,20-bipyridine, ...
