Arrigo, L.M.; Galenas, M; Bassil D.B.; Tucker, S.A.; Kannan, R.; Katti, K.V., Barnes, C.L.; Jurisson, S.S. Fluorescent phosphinimine as possible precursor to an anionic and fluorescent sensor for Tc-99. Radiochimica Acta 2008 (96) 835-844.
The trimethylsilyl-protected phosphinimines (9-anthracenyl)Ph2P=NSiMe3 and (l-naphthyl)Ph2P=NSiMe3 and the ion pairs [(9-anthracenyl)Ph2P=NH2+][MO4-] and [(1-naphthyl)Ph2P=NH2+][MO4-] with M = Re or Tc were synthesized and characterized by H-1 and P-31 NMR, UV-Vis and fluorescence spectroscopy, elemental analysis, and/or single crystal X-ray diffraction. Radiochemical studies performed using Tc-99m and Re-186 as the tracers for Tc-99 and Re found the selectivity of the phosphiniminium cations for pertechnetate in the presence of a variety of anions found in the environment to be excellent.. The crystallographic data reported for the structures are as follows: [(9-anthracenyl)Ph2P=NH2+][ReO4-] (H21C26NO4PRe) 2, monoclinic (P2(1)/n), a= 11.3047(54 angstrom, b= 16.3983(8) angstrom, = 12.2469(6) angstrom, =92.344(1)degrees, Z =4; pairs [(9-anthracenyl)Ph2P=NH2+][TcO4-] (H21C26NO4PTc) 3, monoclinic (P2(1)/n), a = 11.3619(4) angstrom, b = 12.2203(3) angstrom c = 25.7794(13) angstrom, beta= 92.162(1)degrees, Z = 4.
