Metal coordination between polyphenols and metal cations like Fe3 + allows to produce conformal homogeneous and robust coatings on a vast variety of materials. The deposition kinetics and the stability of the obtained films are however only poorly investigated. In the present article it is shown...

Immobilized Tyrosinase enzyme was widely investigated for developing sensitive and specific biosensors for determination of phenolic compounds. However, the performance and stability of these biosensors largely depend upon the used support material and method of enzyme immobilization. In this wo...

Films based on catechols constitute a novel class of surface functionalization methods. Those films are produced by a complexation mechanism with metal cations. The deposition of films is accompagnied with the formation of colloids in solution. As an alternative, herein an electrochemical method...

Tellurium(IV) complexes of formula TeX4L2 and TeX4L′; where L is 2-pyrrolidine-thione (TBuL) or N-methyl-2-pyrrolidine-thione (NMTBuL), L′ is NN′ dimethyldithiooxamide (Me2DH2) and Xz.dbnd;Cl, Br have been prepared and characterised. The IR and Raman spectra of the compounds are reported. The...

Cu(II)-dithiooxamide polymers were prepared by a direct deprotonation of the ligand with a Cu(II) salt. The polymers had a chain length of about 13 units. The undoped polymers showed low electrical conductivity with an Arrhenius-type temperature dependence. Doping of Cu(II)-N,N′-dimethyldithioo...

Increasing evidence indicates that benzothiazoles and thioureas have the ability to inactivate reactive chemical species through their antioxidant activity. In this context, we designed and synthesized two benzothiazole-isothiourea derivatives, (E)-5-((benzo[d]thiazol-2-ylimino)(methylthio)methy...

Benzothiazole (BTHs) are environmental contaminants of emerging concern for which little toxicological information is available. Therefore the toxic potential of twelve BTHs was evaluated with two rainbow trout epithelial cell lines, RTgill-W1 and RTL-W1. The BTHs were benzothiazole (BTH), 3,3′...

Synthetic delivery systems have great potential for overcoming problems associated with systemic toxicity that accompanies chemotherapy with the use of cisplatin and family of platinum anticancer drugs. Mesoporous silicates have been studied in context of drug delivery and drug targeting. In thi...

Mono- and binuclear Pt(II) and Pd(II) complexes with 2,2′-dithiobis(benzothiazole) (DTBTA) ligand are reported. [Pt(DTBTA)(DMSO)Cl]Cl∙CHCl3 (1) and [Pd2(µ-Cl)2(DTBTA)2]Cl2 (2) have been synthesized and structurally characterized by elemental analysis, IR, 1H and 13C NMR spectroscopy, MS spectr...

A novel proton transfer compound (HMeABT)+(HDPC)−·H2O (1) obtained from 2-amino-6-methylbenzothiazole (MeABT) and dipicolinic acid (H2DPC) and its Fe(III), Fe(II), Co(II), Ni(II) and Cu(II) complexes (2–6) have been prepared and characterized by elemental, spectral (1H NMR, IR and UV–Vis) and...

The 1:1 M-ratio reaction between copper(I) bromide or iodide and 4,5-bis(diphenylphosphano)-9,9-dimethyl-xanthene (xantphos) in acetonitrile results in the formation of [CuX(xantphos)] (X = Br, I), which further reacts with N-methylbenzothiazole-2-thione (mbtt) to afford the mononuclear mixed-li...

A highly sensitive and selective naked-eye probe, 2,5-bis[3-benzyl-2-methylbenzothiazole]-croconaine (BMC) for sensing of Fe3+ was synthesized and characterized. The BMC can selectively recognize Fe3+ among the test cations (Ni2+, Mg2+, Cu2+, Ca2+, Na+, K+, Cr3+, Ag+, Ba2+, Zn2+, Pb2+, Al3+, Fe3...

Three hemicyanine dyes containing N-(carboxyethyl)-2-methylbenzothiazolium group and bearing different substituent in p-position of phenyl ring of styryl moiety were readily prepared by a Knoevenagel condensation. Their UV/Vis and fluorescence spectra, aggregation, photostability and association...

The FT-IR (4000–400 cm−1) and FT-Raman (4000–100 cm−1) spectral measurements and complete assignments of the observed spectra of 2-amino-4-methylbenzothiazole (2A4MBT) have been proposed. Ab initio and DFT calculations have been performed and the structural parameters of the compound were dete...

Since their introduction half a century ago, acrylic pressure-sensitive adhesives have been successfully applied in many fields. They are used in self-adhesive tapes, label signs, marking films and protective films as well as in medical pharmaceutical applications for plaster, in dermal dosage s...

The reactions of copper(I) halides, CuX (X = Cl, Br, I) with N-methylbenzothiazole-2-thione (mbtt), independent of the molar ration chosen (1:2 or 1:3), led to the formation of dinuclear complexes of the formula [CuX(mbtt)2]2, whereas the reactions of CuX and mbtt in the presence of two equivale...
