Photolysis of diacylferrocenes and their photo-ligand exchange reactions with 1,10-phenanthroline

The photolysis of 1,1?-diacylferrocenes Fc(COR)2 (Fc = Ferrocenyl, R = CH3,Ph) in the presence of 1,10-phenanthroline (phen) in deoxygenated acetonitrile under irradiation with visible light has been studied. In these photolysis systems the phen has two important roles to play: one is to stabilize the photo-liberated Fe2+ by coordination, and the other is to promote the photolysis through photo-ligand exchange. Under this condition the photoproducts were isolated in definite composition and characterized by single crystal X-ray diffraction, 1H NMR spectroscopy, IR spectroscopy, photolysis-cyclic voltammetry and elemental analysis. The mechanism of the reactions was demonstrated to be charge transfer from metal to acylcyclopentadienyl ring, leading to cleavage of the bond between them. The phen attacks the Fe2+ ion to give the stable tris (1,10-phenanthroline) iron(II) complex cation and the acylcyclopentadienyl ring detaches from the Fe2+ ion, giving the enolate anion in the outer sphere of the complex.

?Development and application of analytical detection techniques for droplet-based microfluidics?-A review

Droplet-based microfluidics has emerged as a powerful platform for high-throughput and low-volume analysis and screening. At present, droplet-based microfluidics is transitioning from the proof-of-concept stage to real-world applications. During this process, analytical detection techniques play indispensable roles for successfully implementing droplet-based chemical or biological assays. In this review, we provide an overview of recent developments in analytical techniques for droplet analysis and elucidate the advantages and limitations of each technique. We cover the majority of technology categories, including optical detection, electrical detection, mass spectrometry, and nuclear magnetic resonance spectroscopy. Additionally, we highlight new research areas that have been enabled by these technical advances. Finally, we provide perspectives on both future technological directions and potential enabling applications.

Nanoparticles based on retinoic acid caped with ferrocenium: A novel synthesized targetable nanoparticle both with anti-cancer effect and drug loading capacity

To date, there is an urgent need for cancer treatment to improve in many ways in order to successfully cure all cancers. Retinoic acid (RA) is a promising anti-cancer drug through influencing cancer stem cells (CSCs). Taxol is a chemotherapy drug for many cancers. To increase the anti-cancer effects of RA and taxol, we created a novel RA nanoparticle, FCRAN, which has the ability of carrying a second anti-cancer drug, taxol, using nanotechnological methods. The results of this study demonstrated that this RA nanoparticle was water-soluble and retained the same effects as RA on cancer cells, such as inhibiting the proliferation of CSCs, inducing the differentiation of CSCs, and enhancing the sensitivity of CSCs to chemotherapeutic drugs. In addition, this RA nanoparticle can be used to carry a second anticancer drug, taxol, to become FCRAN/T and synergistically enhance the anti-cancer effects of both drugs in vivo. Interestingly, the FCRAN/T is a targetable anti-cancer nanoparticle in the presence of higher levels of glutathione (GSH) in cancer cells. Our results demonstrate that our novel synthesized nanoparticles not only retain the RA functions, but can also carry a second anticancer drug to play a synergistic anticancer role with good water solubility, in particular FCRAN/T can target cancer cells. Therefore, our novel synthesized targetable anti-cancer nanoparticles have a better application prospect than that of RA or taxol alone.

Understanding the interaction of thiosulfate with Alloy 800 in aqueous chloride solutions using SECM

In situ scanning electrochemical microscopy (SECM) and scanning tunneling microscopy (STM) assisted scanning reference electrode technique (SRET) were applied for the first time to study the interaction of thiosulfate with Alloy 800 surfaces in aqueous chloride solutions. Electrochemical impedance spectroscopy (EIS) and scanning electron microscope (SEM) were also performed to understand the interaction mechanism. The results showed that the effect of 0.075 mol/L thiosulfate in 0.6 mol/L chloride solutions strongly depended on the potential. There was no aggressive effect at the corrosion potential where the passive layer was intact, but a combined effect was observed with the presence of chloride ions at high potential where the passive layer was broken down.

Application of Biginelli reaction to the synthesis of ferrocenylpyrimidones and [3]-ferrocenophane-containing pyrimido[4,5-d]pyrimidinediones

A series of ferrocene-containing mono- and bis-dihydropyrimidines (DHP’s) were prepared by boric acid mediated three-component Biginelli reactions of formyl- and 1,1?-diformylferrocene, 1,3-dioxo-components and urea. A few further transformations including hydrogenolysis of a benzyl 4-ferrocenyl-DHP-5-carboxylate were also performed. Novel cis-fused saturated pyrimido[4,5-d]pyrimidine-2,7(1H,3H)-diones incorporating [3]-ferrocenophane moiety were constructed by means of iron(III)-catalyzed Biginelli-like condensations of 1,1?-diformylferrocene with urea and in situ generated methyl ketone-derived silyl enol ethers. The structures of the new compounds were established by IR and NMR spectroscopy, including HMQC, HMBC and DEPT measurements.

Symmetry breaking effect in the ferrocene electronic structure by hydrocarbon-monosubstitution: An experimental and theoretical study

We present here the results of a synchrotron radiation-excited UV-photoemission investigation and density functional theory calculations on a structurally related series of organometallic free molecules: ethylferrocene (EtFC), vinylferrocene (VFC), and ethynylferrocene (EFC). This seriesexemplifies the electronic interactions operating when the CC substitue nt group of an aromatic ring is bound to the substrate surface atoms, from a single CC bond to the double and triple CC bond ? systems which are still able to preserve substrate-molecule conjugation. A detailed assignment of the gas phase valence photoelectron spectra is discussed, providing new data on the electronic structure of EtFC and EFC and offering a partial reinterpretation of previous assignments on VFC. The broken symmetry of ferrocene caused by the monosubstitution has notable effectson the removal of the molecular orbital (MO) degeneracy which is found to be especially remarkable for the ferrocenelike e1? MOs. This ef fect is ascribed to the interaction between the aromatic cyclopentadyenyl ring and the substituent through ? hyperconjugation and ? -conjugation mechanisms depending on the nature of the hydrocarbon moiety and its conformational geometry. The vertical ionization energy values of the highest occupied MO for the alkylferrocene and ferrocene free molecules linearly correlate with the redox potential in acetonitrile for ferrocene and the corresponding hybrids obtained by covalently anchoring the free molecule on silicon.

Mapping the antioxidant activity of apple peels with soft probe scanning electrochemical microscopy

We present a non-invasive electrochemical strategy for mapping the antioxidant (AO) activity of apple peels, which counterbalances oxidative stress caused by various external effectors. Soft carbon microelectrodes were used for soft probe scanning electrochemical microscopy (SECM) enabling the gentle and scratch-free contact mode scanning of rough and delicate apple peels in an electrolyte solution. The SECM feedback mode was applied using ferrocene methanol (FcMeOH) as redox mediator that gets electrochemically oxidized at the soft probe and diffuses towards the apple peel where it gets regenerated by certain AOs leading to a redox mediator recycling and increased current signal. The global AO activity in the apple peel including lenticels and regions with artificially degraded AOs were mapped using the soft microelectrodes. Finally, in an apple cross-section the higher and homogeneous AO concentration in the peel with a heterogeneously decaying AO gradient towards the apple inward was visualized, demonstrating the adequate micrometer resolution of the SECM probe and the possibility to get information of the interior AO activity of the apple.
