Blue fluorescent Zinc(II) complexes bearing schiff base ligand for solution-processed organic light-emitting diodes with CIEy ≤ 0.09

Zinc (II) complexes with Schiff bases obtained from N‐[2‐(cyclohexyliminomethyl)‐ or 2‐(4‐cyclohexylphenyliminomethyl) phenyl]‐4‐methylbenzenesulfonamides and their application as highly luminescent blue emitters for OLEDs

“…27,28 The blue light emission of OLEDs is important for their applications in solid-state lighting and full-color flat panel displays. Recent papers [29][30][31] have reviewed a number of blue fluorescent Zn(II) complexes based on Schiff bases for the fabrication of OLEDs, but their quantity and luminescent characteristics are still far from what is required in the industry.…”

New Schiff base salts as sources of blue and green light in the solid state: the role of the anion and protonation

“…Due to their fluorescent characteristics, Schiff bases find numerous applications, for instance in cellular bioimaging 24–27 and as organic light-emitting diodes (OLED), 28–32 selective sensors with high sensitivity for the determination of various cations, e.g. , Al 3+ , 33–35 Fe 3+ , 36–38 Ni 2+ (ref.…”

“…They may affect the spatial separation between the aromatic rings of the cationic Schiff base, possibly create additional molecular interactions, and influence the electron density of the fluorophore. [18][19][20][21][22][23] Due to their fluorescent characteristics, Schiff bases find numerous applications, for instance in cellular bioimaging [24][25][26][27] and as organic light-emitting diodes (OLED), [28][29][30][31][32] selective sensors with high sensitivity for the determination of various cations, e.g., Al 3+ , [33][34][35] Fe 3+ , [36][37][38] Ni 2+ (ref.

Novel Fluorescent Tetrahedral Zinc (II) Complexes Derived from 4-Phenyl-1-octyl-1H-imidazole Fused with Aryl-9H-Carbazole and Triarylamine Donor Units: Synthesis, Crystal Structures, and Photophysical Properties

“…Over the years, several articles have reported the coordination of imidazole-based synthons with a variety of metal ions, including cobalt, nickel, iron, zinc, copper, and iridium, leading to the preparation of stable organic metal complexes [9][10][11][12][13][24][25][26][27]. In particular, d 10 transition zinc (II) complexes have become the focus of an ever-growing research area owing to their attractive luminescence and the low cost of zinc metal sources [2,9,[27][28][29]. This posttransition metal ion can coordinate with four donor atoms, which can easily be increased to five and six, resulting in geometry ranging from tetrahedral to trigonal bipyramid, square pyramidal, and octahedral [2,9,[27][28][29].…”
