A series of novel anthranilic diamide derivatives I (R = 4-Cl-2-Me, 4,6-di-F, 6-Me, etc.; Ar = thiophen-2-yl, 5-bromopyridin-2-yl, iso-Pr, etc.) containing moieties of trifluoromethylpyridine and hydrazone was synthesized and evaluated in vivo for their activities against tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV). Few compounds had the curative activity over 65% against TMV at the concentration of 500 μg/mL, which were significantly higher than those of ningnanmycin (55.0%) and ribavirin (37.9%). Notably, the curative activity of compound I (R = 4-Cl-2-Me, Ar = 5-Me-thien-2-yl) was up to 79.5%, with the EC₅₀ value of 75.9 μg/mL, whereas the EC₅₀ value of ningnanmycin was 362.4 μg/mL and pot experiments also further demonstrated the significantly curative effect of the compound Meanwhile, few compounds displayed more protective activities on TMV than that of ningnanmycin. Moreover few, compounds showed inactivation activity similar to ningnanmycin at 500 μg/mL, and the EC₅₀ value of I (R = 4-Cl-2-Me, Ar = 2-CH₃C₆H₄) (41.5 μg/mL) was lower than ningnanmycin (50.0 μg/mL). The findings of TEM indicated that the synthesized compounds exhibited strong and significant binding affinity to TMV coat protein (CP) and could obstruct the self-assembly and increment of TMV particles.

Four novel compounds (S-DCM-1O, S-DCM-2O, S-DCM-3O, and S-DCM-4O) based on sulfur-substituted dicyanomethylene-4H-chromene (S-DCM) and diarylethene were synthesized. The detailed investigations on the fluorescence spectra, absorption spectra, and time-dependent d. functional theory calculations (DFT/TD-DFT) were presented. The encapsulation of mPEG2000-DSPE effectively increased the solubility of all the as-prepared samples. The results of TEM showed that the nanoparticles had a good dispersion coefficient All the nanomaterials (S-DCM-1O@PEG, S-DCM-2O@PEG, S-DCM-3O@PEG, and S-DCM-4O@PEG) exhibited near-IR emission (650-900 nm) and thus reduced light damage and light scattering for cell imaging in biol. applications. Furthermore, PLL (poly-L-lysine hydrobromide) was used to modify the surface of nanoparticles to facilitate easy uptake by A549 cells by changing their electronegativity. The results suggested that S-DCM-2O@PEG@PLL was a highly suitable candidate for cell imaging because of its low toxicity and excellent biocompatibility.

An efficient synthesis of 2-pyridine derived 4-azido-1,2,3-triazoles I (R = pyridin-2-yl, 6-bromopyridin-2-yl, 8-hydroxyquinolin-2-yl, 1,8-naphthyridin-2-yl, etc.; R¹ = Ph, 4-methylphenyl, 4-fluorophenyl, 3,4-dichlorophenyl, etc.) was elaborated using the corresponding dichlorodiazadienes Cl₂C=C(R)N=NR¹ as precursors.

Elimination of mol. nitrogen promoted the cyclization of nitrene at the azine nitrogen.

A series of Cu(I) pyridyl-imidazole (PyIm) complexes with different aryl groups (Ar = naphthalene (P2), phenanthrene (P3), and anthracene (P4)) attached on the pyridyl ring were synthesized and characterized. The influence of these organic chromophore groups on the photophys. properties of the resulting complexes is investigated. Complexes P2–P4 show stronger light harvesting efficiencies in the visible region compared with the parent complex P1. The emitting state of complex P1 originates from the ³MLCT state with some ³LLCT character, while complexes P2 and P3 predominantly exhibit the ³LLCT character. For complex P4, the triplet emitting state is dominated by the ³(π → π) state localized on the anthryl moiety, together with a lesser contribution form the ³LLCT state. These changes in the photophys. properties were rationalized by DFT and TDDFT methods.

Self-assembly and characterization of a supramol. trigonal bipyramidal iron cage containing an [Fe^III(μ₂-F)₆(Fe^II)₃]³⁺ star motif at its core is reported. The complex can be formed in a one step reaction using an heterotopic ligand that supports site-specific incorporation of iron in three distinct electronic configurations: low-spin Fe^II, high-spin Fe^II and high-spin Fe^III, with iron(II) tetrafluoroborate as the source of the bridging fluorides. Formation of a μ₂-F bridged mixed-valence Fe^II-Fe^III star is unprecedented. The peripheral high-spin Fe^II centers of the mixed-valence tetranuclear star incorporated in the iron cage are highly anisotropic and engage in F-mediated antiferromagnetic exchange with the central Fe^III ion.

Luminescent coinage metal complexes have shown promising applications as electroluminescent emitters, photocatalysts/photosensitizers, and bioimaging/theranostic agents, rendering them attractive alternatives to transition metal complexes based on iridium, ruthenium, and platinum that have extremely low earth abundance. In comparison to the widely studied Au(I) and Cu(I) complexes, Ag(I) complexes have seldom been explored in this field because of their inferior emission properties. Herein, we report a novel series of [Ag(N^N)(P^P)]PF₆ complexes exhibiting highly efficient thermally activated delayed fluorescence by using easily accessible neutral diamine ligands and com. available ancillary diphosphine chelates. The photoluminescence quantum yields (PLQYs) of the Ag(I) emitters are ≤0.62 in doped films. The high PLQY with a large delayed fluorescence ratio enabled the fabrication of solution-processed organic light-emitting diodes (OLEDs) with a high maximum external quantum efficiency of 8.76%, among the highest values for Ag(I) emitter-based OLEDs. With superior emission properties and an excited state lifetime in the microsecond regime, together with its potent cytotoxicity, the selected Ag(I) complex has been used for simultaneous cell imaging and anticancer treatment in human liver carcinoma HepG2 cells, revealing the potential of luminescent Ag(I) complexes for biol. applications such as theranostics. Four silver(I) complexes containing a diphosphoine ligand and an easily synthesized donor-acceptor type diimine ligand were prepared Spectroscopic and theor. studies revealed their efficient photoluminescence via the thermally activated delayed fluorescence mechanism. The selected silver complex afforded good performance in a solution-processed electroluminescent device. The silver complex also demonstrated promising in vitro anticancer activity in human liver carcinoma HepG2 cells, and its location in the cytoplasm instead of the nucleus was visualized by confocal fluorescence imaging.
