Аннотация: A wide series of substituted bipyridines were obtained through the synthesis of 1,2,4-triazines and their aza Diels–Alder reactions. The reported method facilitates the synthesis of functionally diverse bipyridines that provides fine-tuning of photophysical properties of new ligands and their Zn(II) and Ru(II) complexes. Some of substituted bipyridines exhibit ‘off–on’ fluorescence response toward Zn2+ cations.????

    Synthesis of cyclometallated platinum complexes with substituted thienylpyridines and detailed characterization of their luminescence properties [Text] / D. N. Kozhevnikov, V. N. Kozhevnikov, M.

Аннотация: Synthesis of various derivatives of 2-(2-thienyl)pyridine via substituted 3-thienyl-1,2,4-triazines is reported. The final step of the synthesis is a transformation of the triazine ring to pyridine in an aza-Diels-Alder-type reaction. The resulting 5-aryl-2-(2-thienyl)pyridines (HL1-HL4) and 5-aryl-2-(2-thienyl)cyclopenteno[c]pyridines (HL5-HL8) (with aryl = phenyl, 4-methoxyphenyl, 2-naphtyl, and 2-thienyl) were used as cyclometallating ligands to prepare a series of eight luminescent platinum complexes of the type [Pt(L)(acac)] (L = cyclometallating ligand, acac = acetylacetonato). X-ray single crystal structures of three complexes of that series, [Pt(L5)(acac)] = [Pt(5-phenyl- 2-(2-thienyl)cyclopenteno[c]pyridine)(acac)], [Pt(L6)(acac)] = [Pt(5-(4-methoxy)-2-(2-thienyl)cyclopenteno[c]py- ridine)(acac)], and [Pt(L7)(acac)] = [Pt(5-(2-naphtyl)-2-(2-thienyl) cyclopenteno[c]pyridine)(acac)] were determined. Photoluminescence and electronic absorption spectra of the new [Pt(L)(acac)] complexes are reported. For two representative compounds of that series, [Pt(L4)(acac)] and [Pt(L5)(acac)], a detailed photophysical characterization based on highly resolved emission and excitation spectra, as well as on emission decay properties, was carried out. The studies down to low temperature (T = 1.2 K) and up to high magnetic fields (6 = 10 T) allowed us to characterize the three individual substates of the emitting triplet state. In particular, it is shown that the lowest triplet states of [Pt(L4)(acac)] and [Pt(L5)(acac)] are largely ligand-centered (LC) of3jtjt*character, which experience only weak spin- orbit couplings to higher lying singlet states

    1,2,4-Triazine method of bipyridine ligand synthesis for the preparation of new luminescent Eu(III) complexes [Text] / A. M. Prokhorov, V. N. Kozhevnikov, D. S. Kopchuk, D. N. Kozhevnikov // Tetrahedron. - 2011. - Vol. 67, № 3. - P597-607

Аннотация: The ‘triazine’ methodology for the synthesis of functionalised bipyridine ligands proved to be a convenient method for the preparation of luminescent Eu(III) complexes. The approach allows flexible construction of chromophore and coordination sphere with control of photophysical properties. Europium (III) complexes [Eu1]-[Eu5] prepared in this way exhibit intense long-life metal-centered luminescence in aqueous media. The aromatic substituent in the position 5 of bipyridine has a significant influence on luminescence parameters and is used to introduce functionality for bioconjugation. The complexes [Eu4] and [Eu5] bearing primary amine groups are ready-to-go luminescent ‘tags’ for peptide labeling

Аннотация: Calcium yttrium tetrametagermanates Y2CaGe4O12 doped with Er3+ and Er3+/Yb3+ reveal upconversion emission in visible spectral range under near-infrared excitation, ex = 980 nm. For the solid solution ErxY2?xCaGe4O12 concentration dependencies for the green and red lines of the visible emission around 526 nm (2H11/2 4I15/2), 545 nm (4S3/2 4I15/2) and 670 nm (4F9/2 4I15/2) show the optimal value for the sample x = 0.2. The power dependence of the visible luminescence measured at room temperature in the low-power limit indicates two-photon upconversion process. Direct intensification of the upconversion emission signals has been achieved by ytterbium sensitizing. The other upconversion excitation mechanism in Y2CaGe4O12:Er3+ is discussed for an 808 nm incident laser irradiation. A scheme of excitation and emission routes involving ground/excited state absorption, energy transfer upconversion, nonradiative multiphonon relaxation processes in trivalent lanthanide ions in Y2CaGe4O12:Er3+ and Y2CaGe4O12:Er3+, Yb3+ has been proposed. Conditions for visible emission occurrence under quasi-resonance ex = 1064 nm excitation depending on pump power values are considered. In the low-power regime only near-infrared emission caused by the transition 4I13/2 4I15/2 in erbium ions has been detected

OLIGOTHIENYLPYRIDINES -- LIGANDS -- LUMINESCENCE PROPERTIES
Аннотация: Two newly prepared oligothienylpyridines, 5-(2-pyridyl)-5?-dodecyl-2,2?-bithiophene, HL2, and 5-(2-pyridyl)-5??-dodecyl-2,2?:5?,2??-ter-thiophene, HL3, bind to platinum(II) and iridium(III) as NC-coordinating ligands, cyclometallating at position C4 in the thiophene ring adjacent to the pyridine, leaving a chain of either one or two pendent thiophenes. The synthesis of complexes of the form [PtLn(acac)] and [Ir(Ln)2(acac)] (n = 2 or 3) is described. The absorption and luminescence properties of these four new complexes are compared with the behavior of the known complexes [PtL1(acac)] and [Ir(L1)2(acac)] {HL1 = 2-(2-thienyl)pyridine}, and the profound differences in behavior are interpreted with the aid of time-dependent density functional theory (TD-DFT) calculations. Whereas [PtL1(acac)] displays solely intense phosphorescence from a triplet state of mixed ??*/MLCT character, the phosphorescence of [PtL2(acac)] and [PtL3(acac)] is weak, strongly red shifted, and accompanied by higher-energy fluorescence. TD-DFT reveals that this difference is probably due to the metal character in the lowest-energy excited states being strongly attenuated upon introduction of the additional thienyl rings, such that the spin?orbit coupling effect of the metal in promoting intersystem crossing is reduced. A similar pattern of behavior is observed for the iridium complexes, except that the changeover to dual emission is delayed to the terthiophene complex [Ir(L3)2(acac)], reflecting the higher degree of metal character in the frontier orbitals of the iridium complexes than their platinum counterparts.??
