Synthesis of Novel Tetrazole Transition Metal Complexes for Advanced Photonic Applications

Abstract

INTRODUCTIONHeterocycles predominantly containing nitrogen have been renowned as a class of auspicious and handy structures for the novel tetrazole chromophore design (e.g., pyridine tetrazole, bis-tetrazole pyridine, bipyridine tetrazole and terpyridine tetrazole ligands) [1][2][3][4][5][6][7] and synthesis of the elevated energy materials. Due to their higher thermal stability, higher heat of formation of these pyridine based derivatives found much imperative applications embracing the improvement of photoluminescent materials [8], protein crystallography [9] and immense variety of many other applications ranging from material science to medicinal field [10][11][12]. One of the most imperative and sensational applications of tetrazole based derivative as the pyridine tetrazole, which has been set up to display extensive appliances particularly in luminescent applications such as indicators, imaging and signal sensors [13,14].These tetrazole based derivatives can be used as a ligand in the configuration of eclectic range of complexes liable upon the nature of the central metal. Recently, lanthanide complexes equipped, which has publicized much more boosted photo luminescent property [15]. Correspondingly, the complexes

5-(Azulen-1-yldiazenyl)tetrazoles; Syntheses and Properties

“…Good prospects for the practical use of such derivatives have fully encouraged their study. For example, very recently, the transition metal complexes with bidentate ligand 2-(1H-tetrazol-5-yl)pyridine was prepared and used for photonic applications [42]. The researches directed to the behavior of 5,5'-azotetrazoles in the presence of alkaline earth ions have been started since 1898 [13].…”
