Synthesis and Characterization of Donor-pi-Acceptor-Based Porphyrin Sensitizers: Potential Application of Dye-Sensitized Solar Cells

New porphyrin sensitizers based on donor-pi-acceptor (D-pi-A) approach have been designed, synthesized, characterized by various spectroscopic techniques and their photovoltaic properties explored. N,N?-Diphenylamine acts as donor, the porphyrin is the pi-spacer, and either carboxylic acid or cyanoacryclic acid acts as acceptor. All compounds were characterized by using 1H-NMR spectroscopy, ESI-MS, UV-visible emission spectroscopies as well as electrochemical methods. The presence of aromatic groups between porphyrin pi-plane and acceptor group push the absorption of both Soret and Q-bands of porphyrin towards the red region. The electrochemical properties suggests that LUMO of these sensitizers above the TiO2 conduction band. Finally, the device was fabricated using liquid redox electrolyte (I-/I3-) and its efficiency was compared with that of a leading sensitizer. Rooftop ready: New porphyrin sensitizers based on a donor-pi-acceptor approach have been designed, synthesized, and characterized by various spectroscopic techniques and their photovoltaic properties were explored. The electrochemical properties suggest that the LUMO of these sensitizers is above the TiO2 conduction band. The sensitizer HYD4-OC8, has shown an overall conversion efficiency of 9.25 %, whereas the standard sensitizer YD2-O-C8, has shown 9.40 %.

Synthesis and biological evaluation of arylphosphonium-benzoxaborole conjugates as novel anticancer agents

Arylphosphonium-benzoxaborole conjugates have been synthesized as potential mitochondria targeting anticancer agents. The synthesized compounds have been tested for their effects on cell viability in various solid tumor cell lines including breast cancer 4T1 and MCF-7, pancreatic cancer MIAPaCa-2 and colorectal adenocarcinoma WiDr. Compound 6c is designated as a lead compound for further studies due to its enhanced effects on cell viability in the above-mentioned cell lines. Seahorse Xfe96 based metabolic assays reveal that the lead candidate 6c inhibits mitochondrial respiration in 4T1 and WiDr cell lines as evidenced by the reduction of mitochondrial ATP production and increase in proton leak. Epiflourescent microscopy experiments also illustrate that 6c causes significant mitochondrial fragmentation in 4T1 and WiDr cells, morphologically consistent with programmed cell death. Our current studies illustrate that arylphosphonium-benzoxaborole conjugates have potential to be further developed as anticancer agents.

Process for the hydrogenation of imines

The present invention relates to a process for the hydrogenation of an imines with hydrogen in the presence of iridium catalysts. In particular, the present invention relates to a process for the hydrogenation of imines with hydrogen under elevated pressure in the presence of an iridium catalyst and with or without an inert solvent, wherein the reaction mixture comprises a phosphonium chloride, bromide or iodide in the presence of an acid, which can be an organic or inorganic acid soluble or insoluble in the reaction mixture. Suitable imines are especially those that contain at least one group. If the groups are substituted asymetrically and are thus compounds having a prochiral ketitine group, it is possible in the process according to the invention for mixtures of optical isomers or pure optical isomers to be formed if enantioselective or diastereoselective iridium catatalysts are used.

Syntheses, characterization, redox properties, and mixed-valence chemistry of tetra- and hexanuclear diyndiyl complexes

A series of Ru2IIFe2II heterotetranuclear sigma-acetylide complexes [{Cp(dppf)Ru} 2(C?C-R-C?C)] (dppf = 1,1′-bis(diphenylphosphino) ferrocene, R = 0, 1; 1,4-benzenediyl, 2; 1,4-naphthalenediyl, 3; 9,10-anthracenediyl, 4) were prepared and characterized by elemental analyses, ES-MS spectrometry, IR, 1H and 31P NMR, and UV-vis-NIR spectroscopy, and cyclic and differential pulse voltammetry. Reaction of 1 with [Cu(MeCN)4](ClO4) gave Ru2II-Fe 2IICu2I heterohexanuclear compound [{Cp(dppf)Ru}2{Cu(MeCN)}2(C?C-C?C)](ClO 4)2 [5(ClO4)2] through pi-bonding of the acetylides to CuI centers. The structures of 1 and 5(ClO 4)-(SbF6) were determined by X-ray crystallography. Chemical oxidation of 1, 3, and 4 with an equivalent of ferrocenium hexafluorophosphate gave one-electron-oxidized species [{Cp(dppf)Ru} 2(C?C-R-C?C)](PF6) [R = 0, 1a(PF6); 1,4-naphthalenediyl, 3a(PF6); 9,10-anthracenediyl, 4a(PF 6)] with Ru2II,III mixed valence. Electrochemical and visible-infrared spectral studies revealed that the electronic delocalization depends on the R substituent in the bridging ligand C?C-R-C?C. While the mixed-valence compound 1a(PF6) (R = 0) displays an electronically delocalized behavior (class III mixed-valence system), 3a(PF6) (R = 1,4-naphthalenediyl) and 4a(PF6) (R = 9,10-anthracenediyl) may belong to borderline compounds between electronic localization and delocalization.

Living ring-opening metathesis polymerization

Since the discovery of olefin metathesis in the mid-1950s, there has been great interest in using this versatile reaction to synthesize macromolecular materials. More recently, living ring-opening metathesis polymerization (ROMP), a variation of the olefin metathesis reaction, has emerged as a particularly powerful method for synthesizing polymers with tunable sizes, shapes, and functions. The technique has found tremendous utility in preparing materials with interesting biological, electronic, and mechanical properties. This review covers the fundamental aspects of living ROMP and briefly traces its historical development from a catalyst-design perspective. Highlights from the recent literature are used to illustrate the utility of living ROMP in the preparation of macromolecular materials with advanced structures and functions. A discussion on the current status of state-of-the-art catalysts for use in living ROMP reactions as well as opportunities for the future concludes this review.

Synthesis and evaluation of a novel class Hsp90 inhibitors containing 1-phenylpiperazine scaffold

Previously, we identified 1-(2-(4-bromophenoxy)ethoxy)-3-(4-(2- methoxyphenyl)piperazin-1-yl)propan-2-ol (1) as a novel Hsp90 inhibitor with moderate activity through virtual screening. In this study, we report the optimization process of 1. A series of analogues containing the 1-phenylpiperazine core scaffold were synthesized and evaluated. The structure-activity relationships (SAR) for these compounds was also discussed for further molecular design. This effort afforded the most active inhibitor 13f with improved activity in not only target-based level, but also cell-based level compared with the original hit 1.

Ambi-valence taken literally: Ruthenium vs iron oxidation in (1,1?-diphosphinoferrocene)ruthenium(II) hydride and chloride complexes as deduced from spectroelectrochemistry of the heterodimetallic “mixed-valent” intermediates

Combining two different redox-active organometallic moieties, we prepared the compounds [(Cym)RuCl(dpf)](PF6), with Cym = p-cymene = 1-isopropyl-4-methylbenzene, and the diphosphinoferrocenes (dpf) 1,1?-bis(diphenylphosphino)ferrocene (dppf; complex 3), 1,1?-bis(diisopropylphosphino)ferrocene (dippf; complex 4), and 1,1?-bis(diethylphosphino)ferrocene (depf; complex 5) as well as the structurally characterized hydride complex [(C5Me5) RuH(dippf)] (2). In contrast to the case for 2, with an approximately staggered ferrocene conformation, the chloride complexes 3-5 exhibit a syn-periplanar ferrocene arrangement due to a Cl…H(C5H4) interaction in the solid and in solution. The related new compounds [(Cym)RuH(dppf)](PF6) (6) and trinuclear (mu-dpf)[(Cym)RuCl 2)]2 (7-9) were also obtained and identified by 1H and 31P NMR spectroscopy. The redox behavior of 2-6 and of the known [(C5Me5)RuH(dppf)] (1) was investigated using cyclic voltammetry, spectroelectrochemistry in the UV/vis/near-IR and IR regions, and, in part, by EPR. The first oxidation of the areneruthenium compounds 3-6 occurs reversibly at the ferrocene site, while the reduction proceeds via an ECE two-electron pattern under chloride dissociation. These results are compared to those obtained for the pentamethylcyclopentadienide/ hydride complexes 1 and 2, which demonstrate unambiguously the ruthenium center as the site of the first electron loss. The different results for the two kinds of heterodimetallic d5/d6 mixed-valent intermediates, FeIIRuIII for 1+ and 2+ and Fe IIIRuII for 3+-6+, are discussed with respect to the possible uses of such heterodinuclear systems in H 2 conversion catalysis.
