Modulator Effect of Acetic Acid on the Morphology of Luminescent Mixed Lanthanide-Organic Frameworks

Abstract: The control of the size and morphology of Metal-Organic Frameworks is a challenge that must be overcome to ensure the use of these materials in advanced applications. Mixed Lanthanide-Organic Frameworks (MLOFs) were synthesized via solvo(hydro)thermal method and then characterized by PXRD, IR, TG/DTA, SEM and PL spectroscopy. The effect of the modulator (acetic acid) on the morphological characteristics of the obtained powders was investigated. Trivalent terbium ions were successfully incorporated into La-fram… Show more

“…Several monodentate carboxylic acids have been reported in the literature as modulators such as formic acid (FA), acetic acid (AA), benzoic acid (BA), dodecanoic acid, or lauric acid. 11 The use of carboxylate or carboxylic acid modulators is frequent since multitopic carboxylate linkers are one of the main linker types in MOFs. 5,12–14 Basic modulators include pyridine, 15–17 sodium hydroxide, 18 or ammonium hydroxide.…”

“…Redes gadolínio-orgânicas Introdução O elevado potencial das MOFs como materiais emissores de luz tem sido intensamente investigado na última década (Cui et al 2011;Barros et al 2015;Yang et al 2015;Leite et al 2017;Nascimento et al 2017Nascimento et al , 2018 Este interesse é justificado pelo fato que as MOFs apresentam, em geral, elevadas cristalinidade e estabilidade, singularidade na obtenção de diferentes estruturas químicas e uma vasta gama de possíveis aplicações. Desta forma, esses materiais tornaram-se uma importante alternativa no campo de interação, entre a química sintética e a ciência de materiais (Papaefstathiou & MacGillivray 2003), pois apresentam excelente grau de previsibilidade estrutural e ambiente químico bem definido, oferecido para grupos orgânicos e centros metálicos (Cui et al 2011;Wang et al 2011).…”

“…metálicos ou clusters metálicos interconectados através de ligantes orgânicos (Barros et al 2018). Tais estruturas, devido as suas características estruturais e topológicas, além das altas áreas de superfícies, apresentam poros ajustáveis, podendo se estender em mais de uma dimensão (Leite et al 2017;Nascimento et al 2017; Barros et al 2018).…”
