Compound I has a 2D structure based on the heptanuclear discrete building unit {Cd7} with the linear structure. Compound II is a 3D MOF in which the {Cd7} building units are linked into a continuous chain motif due to additional interactions.

The coordination compounds with the general formula [CuLn(POP)]BF4·Solv (n = 1, Solv = 0.5MeCN, complex I; n = 2, Solv = 0.5CH2Cl2, complex II; n = 3, Solv = 1.25Et2O, complex III·Et2O) were prepared by the reaction of CuBF4 with Ln and POP in organic solvents (MeCN/CH2Cl2/Et2O) at 1 : 1 : 1 molar ratio. Compound III·Et2O gradually loses solvate molecules to be converted to the complex [CuL3(POP)]BF4 (III). According to single-crystal X-ray diffraction data, the complexes (I, II, III·Et2O) are ionic; in complex cation [CuLn(POP)]+ the coordination environment of the copper atom is a distorted tetrahedron with CuN2P2 chromophore. The photoluminescence properties of the obtained complexes (I–III) were studied in the solid state and in solution. In the absorption spectra of the complexes, a charge transfer band is observed at 380–385 nm; excitation in this range gives rise to two emission bands at 480 and 650 nm in solution. In the solid state, the complexes show photoluminescence only in the red range (λmax = 600–610 nm) with microsecond lifetimes. It was found that complexes I and III with a more perfect tetrahedral environment have quantum yields an order of magnitude higher than the quantum yield observed for complex II.","PeriodicalId":759,"journal":{"name":"Russian Journal of Coordination Chemistry","volume":"50 8","pages":"567 - 578"},"PeriodicalIF":1.1,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142595487","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}
