Volatile square planar β-imino carbonyl enolato complexes of Pd(II) and Ni(II) as potential MOCVD precursors

Interplay between coordination sphere engineering and properties of nickel diketonate–diamine complexes as vapor phase precursors for the growth of NiO thin films

“…The volatilization onset (1% mass loss) displayed an analogous behaviour (Table 4), and the corresponding values were appreciably lower than those of variously substituted Ni ketoiminate compounds. 12 The melting points of the present complexes were lower than those of Ni(II) ketoiminates, 39 β-enamino ketoesters 28 and dialkylaminoalkoxides, 9 and, for 1 and 2, they were lower than those of many Ni (II) complexes. 1,6,12,26,29,34,[38][39][40]42,43 Isothermal analyses carried out at selected temperatures (see Fig.…”

Tuning Coordination Geometry of Nickel Ketoiminates and Its Influence on Thermal Characteristics for Chemical Vapor Deposition of Nanostructured NiO Electrocatalysts

“…The first proposed Schiff-base type Ni precursor was reported by Basato et al 31 They synthesized several β-imino carbonyl enolato complexes of nickel(II), one of which was successfully used for metalorganic (MO) CVD of NiO. 31 Recently, Chandrakala et al reported the synthesis and thermal evaluation of the square planar bis(N-propyl-3-methylsalicylaldimine)nickel(II), which was employed in a plasma enhanced MOCVD process for the deposition of NiO. 32 These not only require high volatilization temperatures but also resulted in films contaminated with carbon impurities.…”

Construction of Hierarchical Polymer Brushes on Upconversion Nanoparticles via NIR-Light-Initiated RAFT Polymerization

“…Because of the strong affinity of phosphate than that of the carboxylic acid group to UCNPs, alendronate may quickly replace OA on UCNPs by the ligand exchange process and concomitantly introduce the NH 2 group at the surface (note as UCNPs–Ale), which allowed for anchoring CTA molecules by amide conjugation (note as UCNPs–CTA). As shown in the Fourier transform infrared (FT-IR) spectrum (Figure ), in contrast to the UCNPs–OA, the spectrum of UCNPs–Ale shows an emerging peak at 1639 cm –1 (δ N–H ).The wide bands that settled between 1260 and 990 cm –1 are associated with the P–O and P–O–C stretching vibrational in alendronate. , For UCNPs–CTA, the enhanced wide band around 1065 cm –1 (ν CS ) and the new peaks at 3297 cm –1 (ν N–H ) and 1642 cm –1 (ν CO ) clearly show the existence of CTA at UCNPs. − In addition, the UCL spectra changed much after CTA anchoring (Figure ). The UV emission at 365 nm was dramatically eliminated in intensity, whereas the 290 and 350 nm emissions were completely quenched.…”
