Time-dependent density functional theory study of absorption spectra of metallocenes

Extensive TDDFT calculations with various combinations of functionals are carried out to compute low-lying excited states of ferrocene. The combined functional and basis set approach TD-PBE0/6-311++G(d,p) is found to be well-behaved in the calculation of excited states. This choice of functional/basis set can give correct ground-state geometries, excitation energies, absorption spectra, and correct symmetry sequence of low level unoccupied molecular orbitals. This method is applied to the calculation of excitation energies of bis(benzene)chromium and four derivatives of ferrocene and the results are accurate within 0.3 eV. The current study implies that the combination TD-PBE0/6-311++G(d,p) can be used to compute excited state properties of other transition metal complexes.

An HRP-based amperometric biosensor fabricated by thermal inkjet printing

Direct inkjet printing of a complete and working amperometric biosensor for the detection of hydrogen peroxide, based on horseradish peroxidase (HRP), has been demonstrated. The device has been realized with a commercial printer. A thin layer of PEDOT:PSS, which was in turn covered with HRP, was inkjet printed on top of an ITO-coated glass slide. The active components of the device retained their properties after the thermal inkjet printing. The whole device has been encapsulated by means of a selectively permeable cellulose acetate membrane. The successful electron transfer between the PEDOT:PSS covered electrode and the enzyme has been demonstrated, and the biosensor evidenced very good sensitivity, in line with the best devices realized with other techniques, and a remarkable operational stability. This result paves the way for an extensive application of “biopolytronics”, i.e. the utilization of conductive/semiconductive polymers and biologically active molecules to design bioelectronic devices using a common PC, and exploiting normal commercial printers to print them out.

Coupling electrochemistry to capillary electrophoresis-mass spectrometry

Hyphenated techniques have become an important tool in modern analytical research. Among detection techniques, mass spectrometry (MS) plays a dominant role, but efficient analyte separation prior to MS detection is usually desirable, as it provides the basis for reliable qualitative and quantitative determination. However, electrochemical methods offer very versatile approaches for selective sample pretreatment or analyte conversion. This review summarizes recent instrumental analytical developments, which resulted in a special kind of a hyphenated system: electrochemistry-capillary electrophoresis-MS (EC-CE-MS). We discuss the analytical characteristics of this approach and compare them with those of other techniques coupling EC with separation techniques and MS.

Synthesis and electrochemical properties of a series of ferrocene-containing alcohols

A series of primary ferrocenylalcohols, Fc-(CH2)m-OH with m = 1-4 and Fc = ferrocenyl, was synthesised by reduction of the appropriate ferrocenylcarboxylic acids, Fc-(CH2)n-COOH (n = 0-3) and the ester methyl 4-ferrocenylbutanoate with LiAlH4, the reduction of the gamma-ketoacid ferrocylpropanoic acid, Fc-CO-(CH 2)2-COOH, with AlCl3/LiAlH4, and the reduction of ferrocenylcarboxaldehyde, FcCHO, with NaBH4. The secondary ferrocenyl alcohols CpFe(C5H4-CH(OH)-CH 3) and Fe(C5H4-CH(OH)-CH3) 2 were obtained by NaBH4 reduction of acetyl and diacetyl ferrocene. The different reduction methods are compared. The electrochemistry of the alcohols was studied by cyclic voltammetry in CH3CN/0.1 M N(nBu)4PF6 utilising a platinum working electrode. The ferrocenyl group showed reversible electrochemistry with the formal reduction potential (Eo? versus Fc/Fc+) of the ferrocenyl group inversely proportional to side chain length. The influence of the side chain length on Eo? was more pronounced for the acids because the electron-withdrawing properties of the carbonyl group is stronger than that of the alcohol group. Ion pairing was found to play a major role in the electrochemical behaviour of ferrocenylmethanol, Fc-CH 2-OH.

Further solvent-free reactions of ferrocenylaldehydes: Synthesis of 1,1?-ferrocenyldiimines and ferrocenylacrylonitriles

Grinding of 1,1?-ferrocenedicarboxaldehyde with a 2.2 molar equivalent of an aromatic amine in a solvent-free environment provided excellent yields of 1,1?-ferrocenyldiimines. After mixing the aldehyde and amines, a gum or melt formed which eventually solidified to the product. An analytically pure sample of the product was obtained by cold recrystallization. Grinding of ferrocenecarboxaldehyde and 4-substituted phenylacetonitriles under solvent-free conditions provided good yields of the corresponding ferrocenylacrylonitriles. The yield in this reaction was very low when the substituent group para to the acetonitrile group was electron-donating.

Electronic interactions in ferrocene- and ruthenocene-functionalized tetraazamacrcocyclic ligand complexes of FeII/III CoII, NiII, CeII and ZnII

The syntheses of ferrocene- and ruthenocene-functionalized tetraazamacrocyclic ligands and their corresponding transition metal complexes are described. Reaction of N,N?-bis(2-aminoethyl)-1,3-propanediamine (2,3,2-tet) with 1,1?-diformylferrocene and 1,1?-diformylruthenocene produces the ligands fcmac and rcmac in 81-85% yield. Examination of their CuII, NiII, CoII, ZnII and Fe II/III complexes by IR, UV/Vis, EPR and Moessbauer spectroscopy as well as by electrochemical studies suggests electronic communication between the two metal centers of each complex. The molecular structure of [Cu II(fcmac)(FBF3)]BF4, determined by X-ray structure analysis, is reported and shows that the distance between the two metals is 4.54 A. Stability constants, determined by potentiometric titration, indicate that the copper(II) complexes are of similar stability as those with unfunctionalized tetraazamacrocyclic ligands (e.g. cyclam = 1,4,8,11-tetraazacyclotetradecane); stability constants of cobalt(II) complexes are about 2 log units smaller, those of nickel(II) and zinc(II) complexes are reduced by more than 10 log units. This selectivity is discussed on the basis of the structural studies. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005.

Stilbene analogues incorporating the Co(eta4-C 4Ph4)(eta5-C5H4-) end group

A number of organometallic stilbenes of the general type [Co(eta4-C4Ph4)(eta5-C 5H4CHCHR] are reported where R is C6H 4X-4 (X = H, OMe, Br, NO2), 1-naphthyl, 9-anthryl, 1-pyrenyl, (eta5-C5H4)Co(eta4- C4Ph4), and (eta5-C5H 4)Fe(eta5-C5H4Y) {Y = CHO, CHC(CN)2 and CHCHC5H4-eta5) Co(eta4-C4Ph4)}. They were prepared by Wittig or Horner-Wadsworth-Emmons reactions which yield both E and Z or only E products respectively. The isomers were separated and all compounds characterised by standard spectroscopic techniques as well as by X-ray diffraction methods in many cases. The electrochemistry of the stilbene analogues in dichloromethane solution is also reported. In most, the (eta5-C5H4)Co(eta4-C 4Ph4) functional group undergoes a reversible one-electron oxidation. For those molecules that also include (eta5-C 5H4)Fe(eta5-C5H4Y), this is preceded by the reversible oxidation of the ferrocenyl group. Spectroscopic and structural data suggests that for most compounds there is little electronic interaction between Co(eta4-C4Ph 4)(eta5-C5H4) and the R end groups which are effectively independent of one another. The only exceptions to this are Z and E-[Co(eta4-C4Ph4) (eta5-C5H4CHCHC6H 4NO2-4], and [Co(eta4-C4Ph 4)(eta5-C5H4CHCHC 5H4-eta5)Fe{eta5-C 5H4CHC(CN)2}] where the electronic spectra are respectively consistent with a significant Co(eta4-C 4Ph4)(eta5-C5H4)/ NO2 donor/acceptor interaction and a less significant Co(eta4-C4Ph4)(eta5-C 5H4)/C(CN)2 one. However, OTTLE studies show that in the electronic spectra of [Co(eta4-C4Ph 4)(eta5-C5H4CHCHR]+ there are low energy absorption bands (950-1800 nm) which are attributed to R ? Co(eta4-C4Ph4)(eta5- C5H4)+ or, when R is a ferrocenyl-base group, Co(eta4-C4Ph4)(eta5-C 5H4) ? (eta5-C5H 4)Fe(eta5-C5H4Y)+ charge transfer transitions. The ferrocenyl compounds undergo cis/trans isomerisation on the OTTLE experiment timescale.

Electrocatalytic oxidation and voltammetric determination of sulfamethazine using a modified carbon electrode with ionic liquid

A carbon paste electrode was modified with the ionic liquid 1-methyl-3-octyl imidazolium hexafluorophosphate and it was applied for study the electrocatalytic oxidation and voltammetric determination of the drug sulfamethazine. The developed modified electrode was characterized using cyclic voltammetry and scanning electron microscopy. The oxidation of sulfamethazine at the surface of modified electrode occurs at lower potentials than that of an unmodified carbon paste electrode, and both an enhancement of the anodic peak current and a signal narrower and better defined with the modified electrode were observed. Accordingly, a method for the determination of sulfamethazine was developed using differential pulse voltammetry, at pH 11 and with an accumulation time of 3 min. The oxidation of sulfamethazine exhibited a dynamic range between 30 and 300 mug/mL and detection and quantitation limits of 54 and 61 mug/mL, respectively. The method was applied to the determination of sulfamethazine in a veterinary commercial solution.
