1,2,3-Triazoles

, 2008
Rapid progress in the synthetic application of benzotriazole derivatives in the last 20 years has resulted in over 1000 scientific papers on the subject. This fact is reflected in Section 5.01.7, which involves almost a half of the volume of this chapter. The section is arranged according to hybridization of the C-α atom and atomic numbers of the atoms

(E)-1-[5-Methyl-1-(p-tolyl)-1H-1,2,3-triazol-4-yl]-3-{3-[5-methyl-1-(p-tolyl)-1H-1,2,3-triazol-4-yl]-1-phenyl-1H-pyrazol-4-yl}prop-2-en-1-one

IUCrData, 2017
In the title compound, C32H28N8O, the central pyrazole ring makes dihedral angles of 10.04 (14) and 11.37 (13)° with the two 1,2,3-triazole rings.

Light-controlled aggregation and gelation of viologen-based coordination polymers [PDF]

arXiv, 2021
Ditopic bis-(triazole-pyridine)viologens are bidentate ligands that self-assemble into coordination polymers. In such photo-responsive materials, light irradiation initiates photo-induced electron transfer to generate pi-radicals that can self-associate to form pi-dimers.

Gas separation properties of new polyoxadiazole and polytriazole membranes [PDF]

, 1994
The gas separation properties of new aromatic poly-1,2,4-triazole and poly-1,3,4-oxadiazole membranes have been systematically investigated. Various functional groups were incorporated as pendent groups onto the polymer backbone of poly-1,2,4-triazoles ...

Crystal structure, computational study and Hirshfeld surface analysis of ethyl (2S,3R)-3-(3-amino-1H-1,2,4-triazol-1-yl)-2-hydroxy-3-phenylpropanoate

Acta Crystallographica Section E: Crystallographic Communications, 2019
In the title molecule, C13H16N4O3, the mean planes of the phenyl and triazole rings are nearly perpendicular to one another as a result of the intramolecular C—H...O and C—H...π(ring) interactions.

Photoredox Processes in the Aggregation and Gelation of Electron-responsive Supramolecular Polymers Based on Viologens [PDF]

arXiv, 2022
Viologen-based ditopic bis-pyridinyl-triazole bidentate ligands self-assemble in the presence of palladium ions into supramolecular polymers whose structure is imposed by the directed formation of coordination bonds. Light-irradiation of these electron-responsive supramolecular materials triggers a photo-induced electron transfer yielding isolated {\pi}

Imaging of the calcium activated potassium channel 3.1 (KCa3.1) in vivo using a senicapoc‐derived positron emission tomography tracer

Archiv der Pharmazie, Volume 355, Issue 12, December 2022., 2022
The 18F‐labeled derivative [18F]3 of senicapoc was synthesized using the prosthetic group approach with 1‐azido‐2‐[18F]fluoroethane ([18F]6) in a “click” reaction. The biological activity of the new positron emission tomography tracer was evaluated in vitro and in vivo.
