The invention belongs to the technical field of organic complex synthesis, and relates to a light-emitting copper compound based on a benzimidazole diphosphine ligand and a preparation method of the light-emitting copper compound. The molecular formula of the light-emitting copper compound based on the benzimidazole diphosphine ligand is C43H32CuXN2P2, and the structural formula of the light-emitting copper compound based on the benzimidazole diphosphine ligand is shown as a formula I in the specification. The light-emitting copper compound has strong absorption (epsilon> 5 * 10 L.mol . cm ) near 230 nm, and medium-intensity absorption in a range of 280-300nm, the highest luminous quantum efficiency at 293K reaches 71.53% and the longest service life reaches 61.08 microseconds, so that the light-emitting copper compound is an efficient OLED photoluminescent material and can be applied to the field of preparation of OLED luminescent materials.

Twenty-seven novel pyrazole carboxamides with diarylamine-modi?ed scaffold were designed, synthesized and characterized in detail via 1H NMR, 13C NMR, IR and ESI-HRMS. Preliminary bioassays showed that some of the target compounds exhibited good antifungal activity against Rhizoctonia solani, Rhizoctonia cerealis and Sclerotinia sclerotiorum. Among them, compound 9c-7 exhibited the highest antifungal activities against R. solani, R. cerealis and S. sclerotiorum in vitro with IC50 values of 0.013, 1.608 and 1.874?μg/mL, respectively. Notably, compound 9c-7 still presented the highest fungicidal activities against R. solani in vivo with an IC50 value of 22.21?μg/mL. Molecular docking simulation results reveal that compound 9c-7 binds well to the hydrophobic pockets of the receptor protein succinate dehydrogenase. This study suggests that compound 9c-7 could act as a potential fungicide to be used for further optimization.

Since the norepinephrine transporter (NET) is involved in a variety of diseases, the investigation of underlying dysregulation-mechanisms of the norepinephrine (NE) system is of major interest. Based on the previously described highly potent and selective NET ligand 1-(3-(methylamino)-1-phenylpropyl)-3-phenyl-1,3-dihydro-2H-benzimidaz- ol-2-one (Me@APPI), this paper aims at the development of several fluorinated methylaminebased analogs of this compound. The newly synthesized compounds were computationally evaluated for their interactions with the monoamine transporters and represent reference compounds for PET-based investigation of the NET.
