Crystal structure of 4-[(adamantan-1-yl)amino]naphthalene-1,2-dione 

Lamoureux Lamontagne, Guy; Pineda Cedeño, Leslie William; Alvarado Rojas, Mónica (2019)
The title compound, C20H21NO2, an example of a stable 1,2-naphthoquinone, was determined by single-crystal X-ray diffraction analysis at 100 K. This structure illustrates steric buttressing of the adamantanyl group, forcing ...

Neutral organic redox pairs based on sterically hindered hydroquinone/benzoquinone derivatives for dye-sensitized solar cells 

Flores Díaz, Natalie; Soto Navarro, Andrea; Freitag, Marina; Lamoureux Lamontagne, Guy; Pineda Cedeño, Leslie William (2018-06)
Substituted derivatives of hydroquinone/benzoquinone were studied as organic redox mediators in the electrolyte for dye-sensitized solar cells (DSSCs). Thus, di-tert-butylhydroquinone (DTHQ), thymohydroquinone (ThymHQ) and ...

Harnessing titanium dioxide surface toward novel functional materials 

Solera Rojas, José Andrés; Rapp, Christin K.; Rivera Martínez, M. Cinthya; Pineda Cedeño, Leslie William (2015)
The ever-increasing worldwide energy consumption has led the society to quest for novel and functional materials that can be used in the development of solar fuels to some extent lessen the dependence on fossil fuels. In ...

Dye‐sensitized Devices: Photovoltaic and Photoelectrolytic Applications 

Solera Rojas, José Andrés; Ledezma Gairaud, Marisol; Pineda Cedeño, Leslie William (2018-11)
Dye‐sensitized approach along with stability and surface robustness in titanium dioxide (TiO2) against photocorrosion and degradation has been widely studied and applied in several important applications. This chapter ...
