Аннотация: This review is focused on consideration of effects of the nature of N,​N'- and N,​O-​bidentate ligands on the structure and optical properties of their B(III) complexes. It has been established that B(III) complexes with asym. N,​N'- and N,​O-​bidentate ligands, such as ortho-​hydroxyphenyl substituted azaheterocycles and heteryl-​β-​ketoimines, exhibit large Stokes shifts, enhanced intensity, and extended range for luminescence in solns. as well as in solid state, comparable with characteristics of the family of BODIPYs derivs. Complexes of some bidentate ligands can be considered as promising fluorophores for applications in biomedical imaging, electroluminescent, solar cell devices, and other fields.

    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

    Abnormal push-pull benzo[4,5]imidazo[1,2-a][1,2,3]triazolo[4,5-e]pyrimidine fluorophores in planarized intramolecular charge transfer (PLICT) state: Synthesis, photophysical studies and theoretical calculations / O. S. Taniya, V. V. Fedotov, L. K. Sadieva [et al.] // Dyes and Pigments. - 2022. - Vol. 204. - Ст. 110405
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: The combination of excellent luminescence with high solvent polarity effect and aggregation induced emission (AIE) is an ideal combination for creating fluorophores/probes with high microenvironmental sensitivity. However, many push-pull chromophores of the D−A type in common intramolecular charge transfer (ICT) state with a significant solvatochromic effect and AIE activity, have poor luminescent properties. Herein, to overcome this problem by using reactions of nucleophilic aromatic hydrogen substitution (SNH), we have designed a series of novel 4-heteroaryl-substituted 2-aryl-2H-benzo[4,5]imidazo[1,2-a][1,2,3]triazolo[4,5-e]pyrimidine fluorophores possessing a planarized intramolecular charge transfer (PLICT) state. All these fluorophores exhibited high luminescence quantum yields (up to 60%) and large Stokes shift values of up to 7459 cm−1. Among them, the fluorophore 4h was found to exhibit the most pronounced positive solvatochromic effect and the probe 4f exhibited the most pronounced aggregation induced emission characteristics. This AIE behavior was further confirmed by means of time-resolved fluorescence lifetime measurements as well as DFT-assisted geometry optimization studies. In the presence of trifluoroacetic acid (TFA) compound 4h exhibited a well-pronounced acidochromism via visible color change from yellow-green to orange which returned to the original yellow-green solution after the addition of triethylamine (TEA). The Stern-Volmer constant for the probe 4h towards TFA was 38 M−1. Finally, for the compounds 4f, g, h theoretical calculations in the ground and excited states in different solvents were carried out to confirm the PLICT process. Based on all above the herein reported PLICT fluorophores 4a-h can be successfully applied as biological probes and optical switches.

LANTHANIDE COMPLEXES -- ENOL-TAUTOMERISM -- BETA-DIKETONES
Аннотация: Describing the crystal structure, packing, FT-IR, UV-Vis and NMR spectra and thermal properties of new polydentate O-ligand based on aryl-beta-diketone moieties connected by ethylene glycol spacer is the subject of this article. The results of IR, UV-Vis and H-1 NMR spectroscopy as well X-ray crystallography of 1,2-bis[2-(4,4,4-trifluoro-1-hydroxy-3-oxobut-1-enyl)phenoxy]-ethane (BTFPE) indicate that the compound exists in solution and in solid as enol. The crystal structure analysis shows that BTFPE has C2/c group of the monoclinic system. Typical S(6) intramolecular hydrogen bond occurs in each 1,3-diketo moiety. This bond is asymmetric and the H atom is closest to the 0 atom adjacent to the phenyl ring. The packing of the crystal is sustained by numerous C-H center dot center dot center dot O, O-H center dot center dot center dot F, C-H center dot center dot center dot F interactions. In the crystal, supramolecular zig-zag chains are formed along the c-axis. Short contacts interconnect the molecules into a two-dimensional layered structure wherein each molecule is node between chains. According to the thermal investigation this compound is stable up to 200 degrees C in air atmosphere, above this temperature it decomposes. Photoluminescent properties of aluminum(III) and europium(III) complexes of BTFPE were evaluated in chloroform solution and in the solid state. Aluminum complex of BTFPE shows blue luminescence with maximum at 445 nm. Europium complex exhibits intense red color luminescence at 613 nm from central Eu(III) ion through the excitation of the ligand.

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.????
