چکیده
Six new complexes [Cd(tpy)(pfb)2] (1, tpy = 2,2?:6?,2?-terpyridine), [Ln2Cd2(tpy)2(pfb)10] (Ln Eu (2Eu), Tb (2Tb)), [Ln2Cd2(tbtpy)2(pfb)10]·2MeCN (3Eu), (3Tb), tbtpy 4,4?,4?-tri-tert-butyl-2,2?:6?,2?-terpyridine), [Eu2Cd2(tppz)(pfb)10]n (4, tppz 2,3,5,6-tetra-(pyridin-2-yl)pyrazine) based on pentafluorobenzoic acid (Hpfb) have been prepared and investigated. The effect of tridentate ligands geometry heterometallic scaffolds synthesized is discussed. supramolecular crystal structures the compounds are stabilized by ?-?, C-F···?, C-H···O, C-H...F, F….F interactions. Non-covalent interactions studied using Hirschfeld surface analysis. obtained were characterized single-crystal powder X-ray diffraction, luminescence spectroscopy, IR CHN Complexes 2Ln 3Ln exhibit metal-centered photoluminescence, but presence ligand bands indicates incomplete energy transfer from d-block to lanthanide ion.

A new class of highly fluorescent 9,9′-bis-(alkyl)-2,7-diarylfluorene having electron withdrawing or electron donating groups on the p-phenyl positions were synthesized and characterized. The highly luminescent fluorene derivatives, 1–6 showed blue emission (376–416 nm), narrow FWHM (~ 50 nm), high quantum yield (φF = 0⋅12–0⋅87) and short fluorescence lifetimes, τF = 0⋅23–1⋅14 ns. The HOMO leve...
