    • Exceptionally inert lanthanide(III) PARACEST MRI contrast agents based on an 18-membered macrocyclic platform 

      Castro, Goretti; Regueiro-Figueroa, Martín; Esteban-Gómez, David; Bastida, Rufina; Macías, Alejandro; Pérez-Lourido, Paulo; Platas-Iglesias, Carlos; Valencia, Laura (Wiley, 2015-12-14)
      [Abstract] We report a macrocyclic ligand based on a 3,6,10,13-tetraaza-1,8(2,6)-dipyridinacyclotetradecaphane platform containing four hydroxyethyl pendant arms (L1) that forms extraordinary inert complexes with Ln3+ ions. ...
    • Highly stable complexes of divalent metal ions (Mg2+, Ca2+, Cu2+, Zn2+, Cd2+, and Pb2+) with a dota‐like ligand containing a picolinate pendant 

      Regueiro-Figueroa, Martín; Ruscsák, Erika; Fra, Laura; Tircsó, Gyula; Tóth, Imre; Blas, Andrés de; Rodríguez-Blas, Teresa; Platas-Iglesias, Carlos; Esteban-Gómez, David (Wiley, 2014-12)
      [Abstract] The stability constants of complexes of the macrocyclic ligand do3a‐pic4– (H4do3a‐pic = 2,2′,2″‐{10‐[(6‐carboxypyridin‐2‐yl)methyl]‐1,4,7,10‐tetraazacyclododecane 1,4,7‐triyl}triacetic acid) with several divalent ...
    • Lead(II) complexes of lateral macrobicyclic receptors that incorporate a crown moiety and a pyridine head unit 

      Esteban-Gómez, David; Enríquez-Pérez, Teresa; Ferreirós-Martínez, Raquel; Mato-Iglesias, Marta; Platas-Iglesias, Carlos; Blas, Andrés de; Rodríguez-Blas, Teresa (Wiley, 2010-11)
      [Abstract] The coordinative properties towards lead(II) of two lateral macrobicyclic receptors that incorporate either a 1,10‐diaza‐[15]crown‐5 (L7) or a 4,13‐diaza‐[18]crown‐6 (L8) fragment are reported. Spectrophotometric ...
    • Macrocyclic receptor showing improved PbII/ZnII and PbII/CaII selectivities 

      Ferreirós-Martínez, Raquel; Platas-Iglesias, Carlos; Blas, Andrés de; Esteban-Gómez, David; Rodríguez-Blas, Teresa (Wiley, 2010-05-31)
      [Abstract] Herein we report on the macrocyclic receptor N,N′‐bis[(6‐carboxy‐2‐pyridyl)methyl]‐1,10‐diaza‐15‐crown‐5 (H2bp15c5) and its coordination properties towards ZnII, CdII, PbII, and CaII. The stability constants of ...
    • Room temperature molecular up conversion in solution 

      Nonat, Aline; Chan, Chi Fai; Liu, Tao; Platas-Iglesias, Carlos; Liu, Zhenyu; Wong, Wing-Tak; Wong, Wai-Kwok; Wong, Ka-Leung; Charbonnière, Loïc J. (Springer Nature, 2016-06-15)
      [Abstract] Up conversion is an Anti-Stokes luminescent process by which photons of low energy are piled up to generate light at a higher energy. Here we show that the addition of fluoride anions to a D2O solution of a ...
    • Synthesis and characterisation of bismacrocyclic DO3A-amide derivatives – an approach towards metal-responsive PARACEST agents 

      Cakic, Nevenka; Verbić, Tatjana Ž.; Jelić, Ratomir M.; Platas-Iglesias, Carlos; Angelovski, Goran (Royal Society of Chemistry, 2016-02-26)
      [Abstract] Three new bismacrocyclic Ln3+ chelates consisting of triamide derivatives of cyclen with glycine, methyl and tert-butyl substituents (L1–3, respectively) linked to an acyclic EGTA-derived calcium chelator were ...
