Synthesis and characterization of new mixed-valent Mn(II)/Mn(III) and mixed metal Ni/Mn complexes 

Ledezma Gairaud, Marisol; Pineda Cedeño, Leslie William; Aromí, Guillem; Sañudo, E. Carolina (2015)
Microwave assisted synthesis and bench-top reactions are compared for Mn and Mn/Ni reaction systems with substituted salicylic acid (2-hydroxy-6-isopropyl-3-methylbenzoic-acid (SALOH2). When Mn salts are used, the microwave ...

Crystal structures and biological activity of 1,1,4-tri­phenyl-substituted 1,3-enyne com­pounds 

Pineda Cedeño, Leslie William; Arias Echandi, María Laura; Cabezas Pizarro, Jorge A. (2019)
1,3-Enyne structural motifs are versatile building blocks in organic synthesis and occur widely in various natural products with many of them being highly active as cytotoxic macrolides and antitumour antibiotics. This ...

Co-adsorbing effect of bile acids containing bulky amide groups at 3β-position on the photovoltaic performance in dye-sensitized solar cells 

Soto Navarro, Andrea; Alfaro Vargas, Ariel; Soto Tellini, Victor Hugo; Moehl, Thomas; Barea, Eva M.; Fabregat Santiago, Francisco; Pineda Cedeño, Leslie William (2019)
Co-adsorbing molecules attain certain control in the surrounding of the dyes leading to enhanced efficiencies mainly by affecting the recombination of the photogenerated electrons and aggregation of dyes. Bile acids ...
