    • Dual Emission of a Novel (P,N) Re-I Complex: A Computational and Experimental Study on [P,N-{(C6H5)(2)(C5 ... 
      Pizarro, Nancy; Duque, Mario; Chamorro, Eduardo; Nonell, Santi; Manzur Saffie, Jorge; Fuente Urrutia, Julio de la; Günther Sapunar, Germán; Cepeda Plaza, Marjorie; Vega, Andrés (American Chemical Society, 2015)
      The spectroscopic, electrochemical, and photophysical properties of the new complex [P,N-{(C6H5)(2)(C5H4N)-P}Re(CO)(3)Br] are reported. The UV-vis spectrum in dichloromethane shows an absorption maximum centered at 315 rim ...
    • Naphthoxazole-Based Singlet Oxygen Fluorescent Probes 
      Ruiz González, Rubén; Zanocco, Renzo P.; Gidi, Yasser; Zanocco Loyola, Antonio; Nonell, Santi; Lemp Miranda, Else (The American Society of Photobiology, 2013)
      In this study, we report the synthesis and photochemical behavior of a new family of photoactive compounds to assess its potential as singlet oxygen (1O2) probes. The candidate dyads are composed by a 1O2 trap plus a ...
    • Photophysics and Photochemistry of Naphthoxazinone Derivatives 
      Nonell, Santi; Ferreras, Lourdes R.; Cañete, Alvaro; Lemp Miranda, Else; Günther Sapunar, Germán; Pizarro, Nancy; Zanocco Loyola, Antonio (AMER CHEMICAL SOC, 2008-07-18)
      The photophysics and photochemistry of a series of naphthoxazinones have been studied using a combination of methods ranging from steady-state and time-resolved spectroscopic techniques to product analysis. The photophysics ...
    • Solvent and Media Effects on the Photophysics of Naphthoxazole Derivatives 
      Curitol, Manuel; Ragas, Xavier; Nonell, Santi; Pizarro, Nancy; Encinas, María V.; Rojas, Pedro; Zanocco, Renzo P.; Lemp Miranda, Else; Günther Sapunar, Germán; Zanocco Loyola, Antonio (The American Society of Photobiology, 2013)
      The photophysical properties of 2-phenyl-naphtho[1,2-d][1,3] oxazole, 2(4-N,N-dimethylaminophenyl)naphtho[1,2-d][1,3] oxazole and 2(4-N,N-diphenylaminophenyl) naphtho[1,2-d] [1,3]oxazole were studied in a series of ...
    • Structural and photophysical properties of [(CO)(3)(phen) Re(mu-Br)Re(phen)(CO)(3)](+)[(CO)(3)(+)[Re(mu-B ... 
      Gallardo, Héctor; Cepeda Plaza, Marjorie; Nonell, Santi; Günther Sapunar, Germán; Chamorro, Eduardo; Pizarro, Nancy; Vega, Andrés (Elsevier, 2015)
      The multimetallic complex [[(CO)(3)(phen) Re(mu-Br)Re(phen)(CO)(3)][(CO)(3)[Re(mu-Br)(3)Re(CO)(3)]]center dot CH2Cl2 was prepared by direct reaction of (Re(CO)(3)(THF)Br)(2) (THF: tetrahydrofuran) and 1,10-phenanthroline ...
    • Substituent Effect on the Photolability of 4-Aryl-1,4-Dihydropyridines 
      García, Cristóbal; Cabezas, Karina; Nonell, Santi; Núñez Vergara, Luis; Morales Valenzuela, Javier; Günther Sapunar, Germán; Pizarro Urzúa, Nancy Alejandra (The American Society of Photobiology, 2014)
      The electronic nature of substituents attached to the 4-aryl moiety of 1,4-dihydropyridines strongly affects the photophysical and photochemical behavior of these family of compounds. The presence of an electron donor ...
