New dinuclear zinc(ii) complexes with Schiff bases obtained from o-phenylenediamine and their application as fluorescent materials in spin coating deposition

Abstract

Tin fluorescent materials were obtained using a spin coating method.

Experimental and Theoretical Studies of the Optical Properties of the Schiff Bases and Their Materials Obtained from o-Phenylenediamine

“…This feature is important, because the tailored emission can lead to potential applications as optical sensors. Similar behavior was noted for the ligands obtained also from o-phenylenediamine [ 30 ].…”

“…They are connected with π→π*, IL charge transfer transitions in the azomethine, -NH-CH 2 - bonds and aromatic rings. In comparison with the solutions spectra, the bathochromic shift of the absorption bands (250, 344, 482, 506 nm) in the solid state like it was previously observed by us [ 30 ]. It is connected with the highest rigidity of the molecular skeleton of the cyclic molecule.…”

“…In inorganic as well as coordination chemistry, a considerable part of compounds not only have a wide variety of possible donor atoms but can also tune their properties through possible modification of their molecular structures. The introduction of various substituents or rings into the macrocyclic skeleton allows for the modification of the structural and spectroscopic properties of the isolated new compounds [ 27 , 28 , 29 , 30 ].…”

Synthesis, characterization and NLO properties of 1,4-phenylenediamine-based Schiff bases: a combined theoretical and experimental approach

“…, MeCN and methanol, providing information about the nature of the transitions and charge transfer capabilities of the synthesized compounds. 54 The characteristic π–π* transition in –CN– was recorded. The value of the absorption is shifted bathochromically when the solvent polarity increases.…”

Metal Complexes with Schiff Bases: Data Collection and Recent Studies on Biological Activities

“…Binuclear complexes may present in the same or two different metals and are often more interesting than the mononuclear variants in chemical and biological studies. Binuclear complexes with SBs have been widely studied as catalysts [ 79 , 80 , 81 ], in fluorescence and luminescence studies [ 82 , 83 ], and also antimicrobial activities were reported [ 84 , 85 ]. More recently, binuclear complexes with SBs have been suggested for the therapy of COVID-19 disease [ 86 ] on the basis of molecular modeling studies [ 87 ].…”
