Anion-complexation-induced stabilization of charge separation
D'Souza, Francis; Subbaiyan, Navaneetha K.; Xie, Yongshu; Hill, Jonathan P.; Ariga, Katsuhiko; Ohkubo, Kei; Fukuzumi, Shunichi (American Chemical Society, 2009-11-11)A supramolecular oligochromophoric system possessing exclusive binding sites for both a guest electron acceptor and an anionic cofactor species is developed, and anion-binding-induced stabilization of the charge-separated ... -
Enhanced photocurrents via redox modulation by fluoride binding to oxoporphyrinogen in a zinc porphyrin-oxoporphyrinogen surface modified TiO2 supramolecular solar cell
Subbaiyan, Navaneetha K.; Hill, Jonathan P.; Ariga, Katsuhiko; Fukuzumi, Shunichi; D'Souza, Francis (Royal Society of Chemistry, 2011-06-07)A novel approach for improving photocurrent in a supramolecular solar cell, composed of zinc porphyrin-oxoporphyrinogen (ZnP-OxP) surface-modified TiO(2), by redox tuning through fluoride anion binding to the redox active ... -
Supramolecular triad and pentad composed of zinc-porphyrin(s), oxoporphyrinogen, and fullerene(s): design and electron-transfer studies
Schumacher, Amy Lea; Sandanayaka, Atula S. D.; Hill, Jonathan P.; Ariga, Katsuhiko; Karr, Paul A.; Araki, Yasuyaki; Ito, Osamu; D'Souza, Francis (John Wiley and Sons, 2007-01-01)By adopting a "covalent-coordinate" bonding approach, novel supramolecular pentad and triad molecules composed of zinc-porphyrin(s), fullerene(s), and oxoporphyrinogen redox-/photoactive entities have been constructed, and ...
