    • Unexpected Changes in the Population of Coordination Isomers for the Lanthanide Ion Complexes of DOTMA–Tetraglycinate 

      Kumas, Cemile; Fernando, W. Shirangi; Zhao, Piyu; Regueiro-Figueroa, Martín; Kiefer, Garry E.; Martins, André F.; Platas-Iglesias, Carlos; Sherry, A. Dean (American Chemical Society, 2016-09-19)
      [Abstract] Lanthanide complexes with DOTA–tetraglycinate (DOTA-(gly)4) heavily favor the square antiprismatic (SAP) coordination isomer in aqueous solution, a structural feature that has made them useful as water-based ...

      [Abstract] We report a macrocyclic ligand (H3L6) based on a 3,6,10,13-tetraaza-1,8(2,6)-dipyridinacyclotetradecaphane platform containing three acetate pendant arms and a benzyl group attached to the fourth nitrogen atom ...
    • Viologen–cucurbituril host/guest chemistry – redox control of dimerization versus inclusion 

      Dalvand, Parastoo; Nchimi Nono, Katia; Shetty, Dinesh; Benyettou, Farah; Asfari, Zouhair; Platas-Iglesias, Carlos; Olson, Mark Anthony; Trabolsi, Ali; Elhabiri, Mourad (Royal Society of Chemistry, 2021-09-02)
      [Abstract] Two calix[4]arene systems, C234+ and C244+ – where 2 corresponds to the number of viologen units and 3–4 corresponds to the number of carbon atoms connecting the viologen units to the macrocyclic core – have ...
    • Water exchange in lanthanide complexes for MRI applications. Lessons learned over the last 25 years 

      Caravan, Peter; Esteban-Gómez, David; Rodríguez-Rodríguez, Aurora; Platas-Iglesias, Carlos (Royal Society of Chemistry, 2019-06-19)
      [Abstract] The water exchange rates of water molecules coordinated to the metal ion in lanthanide complexes have been profusely investigated during the last 25 years, especially in the case of Gd3+ and Eu3+ complexes. This ...
