Controlled syntheses, structures and photoluminescence of two europium coordination polymers based on 2,4-dcp (2,4-dichlorophenoxyacetate) and 4,4′-bpy (4,4′-bipyridine) ligands

A Photophysical Interpretation of the Thermochromism of a Polyfluorene Derivative–Europium Complex

“…19−22 When the organic part is a π-conjugated polymer, the polymer may emit upon excitation, or the metallic ion, through specific mechanisms of energy transfer, 23,24 and we can get a predominant emission of the polymer chain 25,26 or from the metal ion. 27,28 Rare earth metals, specifically lanthanides, display high luminescence with narrow emission bands. Europium(III) and terbium(III) are attractive luminescent materials because of their red and green emission, respectively.…”

“…Specifically, in the case of emissive properties, the metal–polymer association provides mechanical stability and processability which are not presented by the low molecular mass ligand counterparts. This class of materials has been named metallopolymers, , where the metal is linked directly to the polymer backbone − or as a lateral side chain. − When the organic part is a π-conjugated polymer, the polymer may emit upon excitation, or the metallic ion, through specific mechanisms of energy transfer, , and we can get a predominant emission of the polymer chain , or from the metal ion. , …”

Synthesis, Crystal Structure, Theoretical Study, Thermal ­Behavior, and Luminescence Property of A Bromide‐Bridged Silver(I) Complex with 4, 4′‐Bipyridine

“…Thermal property of complex 1 was evaluated by thermogravimetric analysis (TGA) [25] from 22 to 1000°C in flowing nitrogen at 10°C·min -1 . As shown in Figure 5, the TGA curve of 1 displays the first weight loss of 55.34 % (calcd.…”

Structural analysis of interpenetrated methyl-modified MOF-5 and its gas-adsorption properties

“…One point that remains challenging during their synthesis under hydrothermal conditions is exerting control over the structures of MOFs. The crystallization, structure and morphology of MOFs depend not only on the starting materials, but also on various reaction parameters, such as the temperature, solvent, pH, reaction time, concentration and pressure (Rankine et al, 2012;Wang et al, 2007;Ma et al, 2012;Seetharaj et al, 2019;Hungerford & Walton, 2019). These parameters have profound effects on the structural chemistry of the ligands and the assembly of the ligands with metal centres to form MOFs, which results in structural diversity.…”
