Tris(β-diketonato)europium(III) with a series of variably fluorinated ligands derived from 3,5-heptanedione were synthesised with the aim of determining their hydration state under extraction conditions. The number of coordinated water molecules was determ ...
The segmental bidentate–tridentate–bidentate ligand L2 reacts with MII (M = Cr, Zn) and LnIII (Ln = La, Eu, Gd, Tb, Lu) to give the heterotrimetallic triple-stranded helicates [MLnM(L2)3]7+. For M = ZnII, the isolated complexes ZnLnZn(L2)37 (Ln = ...
The connection of twelve peripheral and divergent dodecyloxy chains to a central tridentate aromatic binding unit provides the dodecacatenar ligand L11, for which room- temperature mesomorphism is detected. An enthalpically unbalanced large melting entropy ...
An integrating sphere for measuring quantum yield comprises a sample holder, for example a capillary (7) adapted to be placed in a quartz tube (12) comprised in the sphere, an inlet opening for introducing an excitation beam (10), and an outlet opening for ...
The need for efficient and photostable lanthanide luminescent materials is dramatically increasing, in particular with respect to their growing application in lighting devices and biosciences. To this end, we have developed a facile synthesis of benzimidaz ...
