    • Additive tuning redox potential in metallacarboranes by sequencial halogen substitution 

      González-Cardoso, Patricia; Stoica, Anca-Lulia; Farràs, Pau; Pepiol, Ariadna; Viñas, Clara; Teixidor, Francesc (Wiley, 2010-04-21)
      The first artificially made set of electron acceptors is presented that are derived from a unique platform Cs[3,3′-Co(C2B9H11)2], for which the redox potential of each differs from its predecessor by a fixed amount. The ...

    • Controlling the pirouetting motion in rotaxanes by counterion exchange 

      Farràs, Pau; Escudero-Adán, Eduardo C.; Viñas, Clara; Teixidor, Francesc (American Chemical Society, 2014-07-25)
      A fine control of the pirouetting motion of rotaxanes was achieved by using a series of metallabisdicarbollides. The latter were used as anions in the protonated form of benzylic amide macrocycle-containing fumaramide ...

    • Metallacarboranes and their interactions: theoretical insights and their applicability 

      Farràs, Pau; Juárez-Pérez, Emilio J.; Lepšík, Martin; Luque, Rafael; Núñez, Rosario; Teixidor, Francesc (Royal Society of Chemistry, 2012-02-14)
      This tutorial review will deal with the study of metallacarboranes and their interactions with other molecules from a theoretical point of view. This contribution is devoted to guide experimental chemists through calculations ...

    • Metallacarboranes as building blocks for polyanionic polyarmed aryl-ether materials 

      Farràs, Pau; Teixidor, Francesc; Kivekäs, Raikko; Sillanpää, Reijo; Viñas, Clara; Grüner, Bohumir; Cisarova, Ivana (American Chemical Society, 2008-09-20)
      Polyanionic species have been obtained in high yield by a new route in the ring-opening reaction of cyclic oxonium [3,3′-Co(8-C4H8O2-1,2-C2B9H10)(1′,2′-C2B9H11)] (2) by using carboxylic acids, Grignard reagents, and ...

    • Relaxed but highly compact diansa metallacyclophanes 

      Farràs, Pau; Teixidor, Francesc; Rojo, Isabel; Kivekäs, Raikko; Sillanpää, Reijo; González-Cardoso, Paul V.; Viñas, Clara (American Chemical Society, 2011-09-09)
      A series of monoansa [μ-1,1′-PR-3,3′-Co(1,2-C2B9H10)2]− and diansa [8,8′-μ-(1″,2″-benzene)-μ-1,1′-PR-3,3′-Co(1,2-C2B9H9)2]− (R = Ph, tBu) cobaltabisdicarbollidephanes have been synthesized, characterized and studied by ...

    • Surfactant behaviour of metallacarboranes. A study based on the electrolysis of water 

      Viñas, Clara; Tarrés, Màrius; González-Cardoso, Patricia; Farràs, Pau; Bauduin, Pierre; Teixidor, Francesc (Royal Society of Chemistry, 2013-11-21)
      [3,3′-Co(1,2-C2B9H11)2]−, [1]−, and its chloroderivatives have been described as displaying surfactant/aggregation properties. We have studied their behaviour as electrolytes in the water electrolysis process. The electrolysis ...

    • Syntheses of C-substituted icosahedral dicarbaboranes bearing the 8-dioxane-cobalt bisdicarbollide moiety 

      Šícha, Václav; Farràs, Pau; Štíbr, Bohumil; Teixidor, Francesc; Grüner, Bohumir; Viñas, Clara (Elsevier, 2009-11-20)
      The treatment of 1,2-, 1,7- and 1,12-carbaborane lithiated isomers with [3,3′-Co-8-(CH2CH2O)2-(1,2-C2B9H10)-(1′,2′-C2B9H11)] (1) at molar ratios 1:1 or 1:2 at room temperature in THF leads generally to the formation of a ...
