Synthesis, structure, optoelectronic properties of novel zinc Schiff-base complexes

Abstract

Two novel zinc Schiff-base complexes, bis-(N-(2-hydroxybenzidene)-p-aminodimethylaniline)zinc(II) (2) and bis-(N-(2-hydroxy-1-naphthidene)-p-aminodimethylaniline)zinc(II) (4) were designed and synthesized. Both the complexes exhibit good solubility in organic solvents and excellent thermal stabilities. A single crystal of 2 was grown and its crystalline structure was determined from X-ray diffraction data. Analysis of the electronic structures of both the zinc complexes calculated by density functional theory reveals a localization of orbital. The UV-Vis absorption and photoluminescence profiles of 4 in thin film are similar to those of 2, but the emission for 4 is red-shifted compared to 2. Three-layered devices with a configuration of ITO/NPB/2/Alq 3 /LiF/Al and ITO/NPB/4/Alq 3 /LiF/Al show a yellow and red emission, respectively. zinc complexes, Schiff-base ligands, electroluminescence Citation:Wang L P, Jiao S B, Zhang W F, et al.

Metal complexes driven from Schiff bases and semicarbazones for biomedical and allied applications: a review

“…; in pharmaceuticals; and as catalyst [53] They are also used in dyes [54], polymers, [54] as well as they are applied in nanotechnology [55], laser [56], transistor [57], in defense as gas generating agents [58], and pyrotechnic mixtures [59]. ; in pharmaceuticals; and as catalyst [53] They are also used in dyes [54], polymers, [54] as well as they are applied in nanotechnology [55], laser [56], transistor [57], in defense as gas generating agents [58], and pyrotechnic mixtures [59].…”

“…Nickel, cobalt, cadmium, and copper complexes with carbohydrazide have been attracted more attention because of its variety of applications in defense. Sonawane et al [57] have reported the copper, nickel, and cobalt carbohydrazide nitrate complexes and studied their burning rate for propellant composition. Such types of compounds are used in Pyrotechnics as they possibly act as flame colorants.…”

From Dual to Discriminatory Sensing of CN‐/F‐Using Isomeric Molecules and Ascertained by Spectroscopic and DFT Methods

“…To endorse the experimental results and to further explore the nature of the optical response of these probes towards anions, both sensors and their deprotonated species were examined theoretically by using DMol 3 package with DFT calculations run through GGA with basis set DNP (double numeric plus polarization) . The optimized structures of (1) , (2) and (3) are shown in Figure .…”

Solution Processable Material Derived from Aromatic Triazole, Azomethine and Tris: Preparation and Hole-Buffering Application in Polymer Light-Emitting Diodes

“…The azomethine bond possesses similar isoelectronic characteristics to vinyl bond, giving rise to similar optoelectronic and thermal properties [20] [21] [22]. However, most of the Schiff base derivatives prepared for OLED applications focused on phosphorescent luminescent materials [23] [24] [25] [26] [27]. To our knowledge, few studies focused on hole-buffering application for optoelectronic devices [15].…”
