Nanoparticles and Thin Films of Silver from Complexes of Derivatives of N-(Diisopropylthiophosphoryl)thioureas

Abstract

The derivatives of N-(diisopropylthiophosphoryl)thiourea RC(S)NHP(S)(O i Pr) 2 (R = C 5 H 11 N, C 5 H 6 N 2 or C 10 H 7 NH 2 ) followed by their complexation with silver are reported. All complexes are decomposed in hot hexadecylamine (HDA) to give HDA-capped silver nanoparticles. The absorption spectra of the HDA-capped silver nanoparticles exhibit surface plasmon resonance (SPR) absorption in the 400-420 nm region. Transmission electron microscopy (TEM) images of all particles are close to spherical in shape; with sizes ranging from 17 to 20 nm. The X-ray diffraction (XRD) patterns of the silver nanoparticles obtained from all three complexes could be indexed to face centered cubic silver. Scanning electron microscopy (SEM) image confirmed the spherical shape of the particles. The silver complex of 1-naphthylamine was also used to deposit thin films of silver by the aerosol-assisted chemical vapor deposition (AACVD).

Self-assembled monolayer structures of hexadecylamine on Cu surfaces: density-functional theory

“…Hexadecylamine (HDA) and long-chain alkylamines, in general, are widely used capping agents, or structure-directing agents (SDA), for the solution-phase synthesis of various metal nanostructures. For example, nanocrystals of Cu, [1][2][3][4][5][6][7][8][9][10][11][12][13] Ni, 14,15 Ag, 12,[16][17][18] Pd, 19 Ru, 20 Au, 12,16 and Pt 21,22 have been synthesized in the presence of HDA. The synthesis of pure Cu nanocrystals is particularly challenging because Cu oxidizes easily.…”

Synthesis of a new α-aminophosphonate library. Crystal structure of p-XC6H4–NH–CH(p-BrC6H4)–P(O)(OiPr)2 (X = H, Br, CH3O)

“…The interest is caused not only from the fact that these compounds show a rich coordination chemistry but also from the applications of (thio)phosphoryl(thio)ureas as agents for extraction and transporting different cations, anions and organic molecules [14], and as ligands in metal complexes used as single source precursors for thin films, nanocrystals and semiconductors [15]. One of the pathways to new (thio)phosphoryl (thio)urea ligands is the modification of amines (Scheme 1).…”

N,N′-Diarylformamidine Dithiocarbamate Ag(I) Cluster and Coordination Polymer

“…Silver(I) complexes have been applied in various fields, therefore, attracting great attention due to their structural features and functional considerations [1][2][3]. They have been tested as fluorescent materials [4], semiconductors [5,6], source of nanomaterials [7] and biological imaging agents [8] due to their interesting and fascinating physicochemical properties. Ag(I) complexes have also shown potential medical applications, most especially as antibacterial [9,10], antifungal [11], anticancer [12], and antimalarial agents [13].…”
