The structure of I was comprehensively analyzed using single crystal X-ray diffraction (SXRD), X-ray powder diffraction (XRPD), elemental analysis revealed that I is an ionic compound, comprising the anion [H(NiO6)Mo6O18(As3O3)2]3– and three counter cations ({text{NH}}_{4}^{ + }). Notably, I exhibits efficient and selective adsorption of Methylene Blue (MB), allowing its separation from other dyes. Furthermore, I exhibited good stability and recyclability in the adsorption of Methylene Blue, which was confirmed by five cycle tests.

The introduction of a biphenyl fragment into the β-diketone ligand extends the π-conjugation system and enhances light absorption in the near-visible region, while the use of Phen as an ancillary ligand eliminates inner-sphere water or alcohol molecules that typically cause luminescence quenching. Structural studies revealed that the biphenyl moiety adopts a twisted conformation, enabling π–π stacking interactions with the phenanthroline ligand. This stacking leads to the formation of intermolecular charge-transfer states, as evidenced by features observed in the excitation spectra. The europium complex [Eu(BPhTFB)(Phen)] exhibits intense red emission characteristic of the 5D0 → 7FJ transitions, with an internal quantum yield of 57% and an overall luminescence quantum yield of 32%. The gadolinium analogue serves as a non-luminescent reference, confirming the ligand-centered origin of the sensitization process. The combined structural and photophysical data demonstrate that introducing extended aromatic substituents and appropriate ancillary ligands effectively enhances the luminescence performance of europium β-diketonate complexes, making them promising candidates for use in photonic and sensing applications.","PeriodicalId":759,"journal":{"name":"Russian Journal of Coordination Chemistry","volume":"51 12","pages":"1067 - 1073"},"PeriodicalIF":1.1,"publicationDate":"2026-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
