Tuning the Morphology of Spray‐Dried Supraparticles: Effects of Building Block Size and Concentration
Autor: Huanhuan Zhou, Rosa Pujales‐Paradela, Philipp Groppe, Susanne Wintzheimer, Karl Mandel
Tuning the morphology of supraparticles can crucially influence their final properties and is, thus, important for their application in chemical, pharmaceutical, and food industries. The present study reveals how varied nanoparticle sizes, concentrat

Autor: Rosa Pujales-Paradela, David Esteban-Gómez, Paulo Pérez-Lourido, Mauro Botta, Carlos Platas-Iglesias, Tanja Savić, Goran Angelovski
Publikováno v: Inorganic Chemistry
We present a detailed study of the lanthanide(III) complexes with cyclen-based ligands containing phenylacetamide pendants that incorporate CF3 group(s) at different distances from the metal ion. The complexes exhibit square-antiprismatic coordinatio

Gadolinium(III)‐Based Dual1H/19F Magnetic Resonance Imaging Probes
Autor: Tanja Savić, Goran Angelovski, David Esteban-Gómez, Carlos Platas-Iglesias, Fabio Carniato, Rosa Pujales-Paradela, Mauro Botta
Publikováno v: Chemistry – A European Journal
We present two novel octadentate cyclen-based ligands bearing one (L1 ) or two (L2 ) phenylacetamide pendants with two CF3 groups either at positions 3 and 5 (L1 ) or 4 (L2 ). The corresponding Gd3+ complexes possess one coordinated water molecule, a

Water soluble Eu(III) complexes of macrocyclic triamide ligands: Structure, stability, luminescence and redox properties
Autor: Avinash Lakma, Rabindra Nath Pradhan, Goran Angelovski, Rosa Pujales–Paradela, Dragana D. Stojkov, Tatjana Ž. Verbić, Akhilesh Kumar Singh, Carlos Platas–Iglesias, Sayed Muktar Hossain
Publikováno v: Inorganica Chimica Acta
Two macrocyclic triamide octadentate chelator scaffolds L1 and L2 were synthesized, characterized by several spectroscopic techniques, and their pKa values were determined by potentiometric titration. Using these ligands, two water soluble paramagnet
