A multifunctional Eu-MOF with multi-color and proton conduction switching and its anti-counterfeiting applications Dyes Pigments (IF 4.5) Pub Date : 2024-02-23 Kang-Jing Li, Yuan Shen, Shi-Li Li, Xian-Ming Zhang
Lanthanide metal-organic frameworks (Ln-MOFs) have exhibited remarkable capabilities in color change, luminescence, proton conduction through the strategic modification of metal nodes, organic ligands and channels or pores. By modifying the electron-deficient bipyridinium to contain carboxylic acid moieties and coordinating them with the luninescent Eu ion, a unique and versatile Eu-MOF has been synthesized

Modulation of lanthanide luminescence by carbamoylmethylphosphine oxide ligand: A theoretical study Dyes Pigments (IF 4.5) Pub Date : 2024-02-23 Tsvetan Zahariev, Pencho Beykov, Natasha Trendafilova, Ellie Uzunova, Ivelina Georgieva
The antenna capacity of Phenacyldiphenylphosphine oxide (), combining C=O and P=O donor groups was established by theoretical examination of its chromophore properties, binding ability to encapsulate and stabilize lanthanide complexes and potential to sensitize the Eu and Tb luminescence in Eu(Phenac)(NO)(HO) (), Eu(Phenac)(NO) (), Eu(Phenac)(NO) () and Tb(Phenac)(NO)(HO) () complexes in vacuum, solution
