The synthesis of InP nanofibers via a new Ullmann-type reaction of indium nanoparticles with tri(m-tolyl)phosphine (P(PhMe)3) was typically performed to illustrate an alternative route for the preparation of nanostructured metal phosphides, including III-V (13-15) and transition-metal phosphides. Triarlyphosphine compounds such as other two tri(m-tolyl)phosphine isomers, diphenyl(p-tolyl)phosphine, and triphenylphosphine were comparably employed to synthesize InP nanocrystals. From the aspect of the carbonization of triarlyphosphines, Raman spectroscopy and thermo-gravimetric analysis (TGA) investigations of the InP products showed that the stability of these triarlyphosphines conformed to the order of tri(p-tolyl)phosphine ? tri(o-tolyl)phosphine < diphenyl(p-tolyl)phosphine < tri(m-tolyl)phosphine < triphenylphosphine. The correlation between the stability of triarlyphosphines and the growth of InP nanocrystals was investigated, and experimental results showed that the relatively stable triarlyphosphines (tri(m-tolyl)phosphine and triphenylphosphine) were favorable for the preparation of one-dimensional (1D) InP nanostructures (nanofibers and nanowires). The reactivity (stability) of triarlyphosphines was also compared with those of P(SiMe3) 3 (typically see: J. M. Nedeljkovic, O. I. Micic, S. P. Ahrenkiel, A. Miedaner and A. J. Nozik, J. Am. Chem. Soc., 2004, 126, 2632) and P(C8H 17)3 (C. Qian, F. Kim, L. Ma, F. Tsui, P. D. Yang and J. Liu, J. Am. Chem. Soc., 2004, 126, 1195) according to the difference in preparative temperature for phosphide synthesis. Raman and photoluminescence properties of the as-synthesized InP nanocrystals were further studied, and the synthetic mechanism of our method was reasonably investigated by GC-MS analysis. Moreover, the current route was successfully extended to prepare GaP, MnP, CoP and Pd5P2 nanocrystals. The Royal Society of Chemistry 2010.

Reaction of diphenylphosphane with glyoxylic acid hydrate in diethyl ether furnished diphenylphosphanylglycolic acid 1 and in a 1:2 molar ratio almost quantitatively the zwitterionic phosphonioglycolic acid glycolate 2. Tertiary phosphanes with aryl or alkyl groups (phenyl, m/p-tolyl, p-anisyl, n-butyl, tert-butyl) react similarly to triorganylphosphonioglycolates 3a-h, which like 2 precipitate from the etheral solutions of the reactants. Tri-n- butylphosphonioglycolate (3e) forms an ionic liquid and tri-tert- butylphosphonioglycolate (3f) a viscous product whereas the other phosphonioglycolates are solids. Yields and stabilities of 3a-e increase with the P-basicity of the starting phosphane whereas bulky groups like tert-butyl cause destabilization. Compound 2 is the most stable phosphonioglycolate with only minor amounts of 1 in the solvolysis equilibrium in D2O. The triaryl and tributylphosphonioglycolates 3a-f decompose in protic solvents with recovery of tertiary phosphanes. On heating at 100 C the compounds decompose to the corresponding phosphine oxides, minor amounts of glycolic acid and unidentified products.

Six polyfluorene derivatives, P1?P6, were synthesized and investigated as responsive materials for the optical sensing of metal ions in an aqueous medium. They were designed by combining carbazole with fluorene units within the backbone. Carbazole was N-functionalized with three coordinating groups, 2-pyridyl-benzimidazole (P1 and P4), 2-phenyl-benzimidazole (P2 and P5) and 4-phenyl-terpyridyl (P3 and P6), respectively. P1?P3 are random copolymers with fluorene:carbazole ratios of 9:1 for P1 and P2, and 9.7:0.3 for P3; P4?P6 are the corresponding alternating polymers. This design lead to polymers made of a conjugated backbone and pendant coordinating groups. The optical properties of the monomers were impacted in various ways by metal ions, and the formation of the [NiM3]2+ and [ZnM3]2+ and [ZnM32]2+ were evidenced with association constants of 105.22, 106.45 and 1014.0, respectively. The emission of the polymers was afterwards found to be influenced by theses metal ions with different sensitivity and selectivity. P1 was found to be more sensitive to the Ni2+ and Cu2+ ions with a better selectivity for Ni2+. Emission of the corresponding alternating polymer P4 was more efficiently quenched by these two ions with respect to P1, in addition of being sensitive to the Ca2+ and Al3+ ions. P3 showed sensitivity to the Ni2+, Cu2+, Al3+, Ca2+, and Zn2+ ions. The luminescence of P6 was much more pronounced with the Ni2+, Cu2+, Cd2+, Zn2+, Al3+, Fe2+, and Fe3+ ions with respect to P3. More remarkably, the presence of the Zn2+ or Cd2+ ions resulted in a new emission band, leading to the possibility to selectively sense these two ions. Relatively high Stern-Volmer constants (in the 106?105 range) were obtained, and sensitivities down to the ppb level were reached, especially for the Ni2+ ion. Influence of both the coordinating group and the polymer backbone on the polymers sensitivity and selectivity was emphasized. Finally, the recyclability of some representative optical sensors was shown both in solution and in the solid state. In particular, thin films were shown to be easily regenerated, which opens the way to the elaboration of reusable optical sensors.

Laser flash photolysis (LFP) time-resolved UV-VIS (TRUV) spectroscopy was carried out on the acetonitrile solution of triarylphosphines, Ar3P, in an oxygen, air, or argon atmosphere. The transient absorption most likely from a triarylphosphine radical cation, Ar3P·+, appeared on the TRUV, which disappeared with the rate depending on the concentration of O2.
