So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Zanarini, Simone; Bard, Allen J.; Marcaccio, Massimo; Palazzi, Antonio; Paolucci, Francesco; Stagni, Stefano researched the compound: 5-(4-Pyridyl)-1H-tetrazole( cas:14389-12-9 ).Safety of 5-(4-Pyridyl)-1H-tetrazole.They published the article 《Ruthenium(II) Complexes Containing Tetrazolate Group: Electrochemiluminescence in Solution and Solid State》 about this compound( cas:14389-12-9 ) in Journal of Physical Chemistry B. Keywords: ruthenium bipyridine terpyridine tetrazolate electrochemiluminescence phosphorescence. We’ll tell you more about this compound (cas:14389-12-9).
The authors report the results about the solution and solid-state phosphorescence emission properties of six RuII complexes containing various 5-substituted tetrazolate ligands. The photo- and electrochemiluminescence spectra of all compounds revealed a red shifted emission with respect to the Ru(bpy)32+. Significant changes to the light emission energy and to the efficiency and sensitivity to oxygen were also determined by varying the nature of the substituent ring of the tetrazolate ligand. Light-emitting solid devices with active layers containing solid films of the same complexes were prepared, and preliminary studies of their electroinduced emission properties were performed. The electrochemiluminescence (ECL) emission intensity of two of the six complexes was of the same order of magnitude as the reference Ru(bpy)32+.
From this literature《Ruthenium(II) Complexes Containing Tetrazolate Group: Electrochemiluminescence in Solution and Solid State》,we know some information about this compound(14389-12-9)Safety of 5-(4-Pyridyl)-1H-tetrazole, but this is not all information, there are many literatures related to this compound(14389-12-9).
