“…Special care was taken in the purification of the compounds and solvents used. Perylene (Sigma, St. Louis, MO, USA) was purified by multiple recrystallization and silica and alumina chromatography [30], followed by gradient sublimation under reduced pressure at~110 • C. The tetrabutylammonium salts of gold and platinum were synthesized as described [31,32] and recrystallized several times from acetone under argon atmosphere. Dichloromethane was distilled, dried and passed through a column of activated alumina just before use.…”

The Solid Solutions (Per)2[PtxAu(1−x)(mnt)2]; Alloying Para- and Diamagnetic Anions in Two-Chain Compounds

Abstract:The α-(Per) 2 [M(mnt) 2 ] compounds with M = Pt and Au are isostructural two-chain solids that in addition to partially oxidized conducting perylene chains also contain anionic chains that can be either paramagnetic in the case of M = Pt or diamagnetic for M = Au. The electrical transport and magnetic properties of the solid solutions (Per) 2 [Pt x -Au (1−x) (mnt) 2 ] were investigated. The incorporation of paramagnetic [Pt(mnt) 2 ] impurities in the diamagnetic chains, and the effect of breaking the paramagnetic chains with diamagnetic centers for the low and high Pt range of concentrations were respectively probed. In the low Pt concentration range, there is a fast decrease of the metal-to-insulator transition from 12.4 K in the pure Au compound to 9.7 K for x = 0.1 comparable to the 8.1 K in the pure Pt compound. In the range x = 0.50−0.95, only β-phase crystals could be obtained. The spin-Peierls transition of the pure Pt compound, simultaneous with metal-to-insulator (Peierls) transition is still present for 2% of diamagnetic impurities (x = 0.98) with transition temperature barely affected. Single crystal X-ray diffraction data obtained a high-quality structural refinement of the α-phase of the Au and Pt compounds. The β-phase structure was found to be composed of ordered layers with segregated donors and anion stacks, which alternate with disordered layers. The semiconducting properties of the β-phase are due to the disorder localization effects.

“…Solvents were purchased from Pharmco-AAPER and reagents were purchased from Aldrich and used as received. [Pt(pyz) 4 ](BF 4 ) 2 , 4, [23] [Pt(NCMe) 4 ](BF 4 ) 2 , [24] and (TBA) 2 [Pt(mnt) 2 ], [25] were synthesized according to previously published work. Electrochemical measurements were conducted using a CHI 620B electrochemical analyzer in a 0.1 M tetra-n-butylammonium hexafluorophosphate (Bu 4 NPF 6 ) solution using a platinum disk working electrode, a platinum wire counter electrode, and an Ag/AgCl reference electrode with a scan rate of 0.1 V/s.…”

Synthesis and Biological Analysis of Thiotetra(ethylene glycol) monomethyl Ether-Functionalized Porphyrazines: Cellular Uptake and Toxicity Studies

et al. 2008

The porphyrazines (pzs), a class of porphyrin analogues, are being investigated for their potential use as tumor imaging/therapeutic agents. We here examine six peripherally-functionalized M[pz(AnB4-n)] pzs with n=4, 3, or 2 (in a trans conformation) and M = H2 or Zn, where A is an [S((CH2)2O)4Me]2 unit and B is a fused β,β′-diisopropyloxybenzo group. Cell viability/proliferation assays and fluorescence microscopy were carried out in both tumor and normal cells. Dark toxicity studies disclosed that four of the compounds exhibited toxicity in both normal and tumor cells; one was nontoxic in both normal and tumor cells, and one was selectively toxic to normal cells. Additionally, three of the pzs showed enhanced photo-induced toxicity with these effects in some cases being observed at treatment concentrations of up to ten-fold lower than that needed for a response in Photofrin. All six compounds were preferentially absorbed by tumor cells, suggesting that they have potential as in vitro diagnostic agents and as aids in the isolation and purification of aberrant cells from pathological specimens. In particular, two promising diagnostic candidates have been identified as part of this work.
