Bimolecular fluorescence quenching of benzoxazole/benzothiazole-based functional dyes

Four dyes that belong to the group of hemicyanines and possess benzoxazole and benzothiazole moieties are synthesised and described. The spectroscopic properties of these compounds in 1-methyl-2-pyrrolidinone (MP) were studied. Synthesised dyes absorb in the UV-Vis region. The emission spectra are broad with a maximum located at approximately 500-520 nm. The deactivation of excited states of the synthesised molecules by various quenchers is also presented. The fluorescence quenching parameters were calculated using the Stern-Volmer equation. It was found, that the fluorescence quenching of the excited dye by quencher molecules occurs. The fluorescence quenching rates (k(q)) are about 10(10) M-1 x s(-1). (C) 2020 Elsevier B.V. All rights reserved.

Substituted 2-Phenacylbenzoxazole Difluoroboranes: Synthesis, Structure and Properties

Novel fluorescent dyes such as benzoxazole-boron complexes, bearing beta-ketoiminate ligands, have been synthesized and characterized with a focus on the influence of a substituent on the basic photophysical properties. H-1, B-11, C-13, N-15, and F-19 nuclear magnetic resonance (NMR) spectra of substituted 2-phenacylbenzoxazole difluoroboranes have been recorded and discussed. It is worth mentioning that a high correlation coefficient was found between N-15-NMR parameters and substituent constants. The photophysical properties of these new dyes have been investigated by fluorescence and ultraviolet-visible (UV-Vis) absorption spectroscopy. The geometry optimization, vibrational spectra, and the HOMO and LUMO energies were calculated based on density functional theory with the use of the B3LYP functional and 6-311++G(d,p) basis set.

Construction of S-CF2/O-CF2 bonds via inter intramolecular radical nucleophilic substitution reaction

A facile and efficient method for construction of S-CF2 or O-CF2 bonds through intermolecular radical nucleophilic substitution (S(RN)1) reaction of 2-bromo-2,2-difluoro-N-phenylacetamide and thiophenols or phenols was developed, which has also been successfully utilized in the intramolecular S(RN)1 reaction to generate a new O-CF2 bonds for synthesis of biologically important 2,2-difluoro-2H-benzo [1,4]oxazin-3-one. The protocol enables an efficient access to gem-difluoromethylene-containing thioethers or ethers and oxazin heterocycles with good to excellent yields by inter/intramolecular radical nucleophilic substitution reaction under mild reaction conditions.

Access to C4-arylated benzoxazoles from 2-amidophenol through C-H activation

A Pd-catalyzed aerobic approach to access C4-aryl benzoxazoles by tandem C-H ortho-arylation and acid-mediated annulation of 2-amidophenol has been presented. The directing potential of the -NHCOR group over the -OH group was exploited for selective arylation adjacent to the amide group. Deuterium labeling experiments suggest that palladation predominantly occurs adjacent to the -NHCOR group and is the key step during benzoxazole formation. One-pot hydrolysis of the resulting C4-arylated benzoxazole was also accomplished to access structurally challenging 3-aryl aminophenols for further applications.

Transition metal-catalyzed alpha-alkylation of amines by C(sp(3))-H bond activation

alpha-Substituted amines are present in a myriad of biologically active natural and synthetic products. With the objective of developing atom-economical reactions, a panel of synthetic methods allowing the direct functionalization of C(sp(3))-H bonds adjacent to the nitrogen atom have been developed. The field remains dominated by the sequence a-lithiation/addition on an electrophile even if the use of reactive organolithium reagents is not compatible with all functional groups. Over the past ten years, an increasing interest has been devoted to metal-catalyzed C-H-activation, some studies being specially dedicated to C(sp(3))-H bond activation. Notably, this approach has been envisioned to perform direct alpha-functionalization of amines. The aim of this article is to give an overview of synthetic methods for transition metal-catalyzed alpha-allcylation of amines by C(sp(3))-H bond activation. (C) 2018 Published by Elsevier Ltd.

Micro-structured fluorescent powders for detecting latent fingerprints on different types of surfaces

Benzazole dyes have shown great potential for application in different fields of science due to their intense and stable photoluminescence properties, associated with high sensitivity. In this study, we developed and evaluated micro-structured fluorescent powders based on benzazole dyes for fingerprint detection on different types (porous and non-porous) and colors (dark, white, and multi-colored) of surfaces. The new micro-structured powders were obtained by embedding a small amount of benzazole dye into a silica matrix (1:100 and 1:300 mass ratio) using an aqueous solution or ethanol under ambient conditions. The photophysical properties were characterized by UV-vis absorption and fluorescence emission spectroscopy. To assess the efficiency of these proposed powders, comparisons were performed with commercially available black, white, and fluorescent powders (Sirchie (R)) for different types of surfaces. The developed micro-structured powders showed intense fluorescence emission in the blue-green region, and a sharp contrast with the fingerprint residues when exposed to long wavelengths of UV light (365 nm) was observed, producing distinct ridge details on all examined surfaces.

(Pyridyl)benzoazole ruthenium(III) complexes: Kinetics of ligand substitution reaction and potential cytotoxic properties

The present work investigates the kinetics of ligand substitution reaction and anticancer activities of the complexes, [{2-(2-pyridyl) benzimidazole} RuCl3] (C1), [{2-(2-pyridyl) benzoxazole} RuCl3] (C2), [{2-(2-pyridyl) benzothiazole} RuCl3] (C3) and [{1-propyl-2-(pyridin-2-yl)-H-benzoimidazole} RuCl3] (C4). The substitution kinetics reaction of the complexes with the three bio-relevant nucleophiles, viz.: thiourea (TU), 1, 3-dimethyl-2-thiourea (DMTU) and 1, 1, 3, 3-tetramethyl-2-thiourea (TMTU) was investigated under pseudo first-order conditions as a function of concentration and temperature using UV-Visible spectrophotometer. The substitution of the coordinated chloride was controlled by the electronic effect. The order of reactivity of the complexes with the nucleophiles is in the form C1 > C2 > C3 > C4 which is in line with the density functional theory (DFT) studies. The complexes showed minimal anticancer activity against the HeLa cell line, which is in contrast to the molecular docking experiments that exhibited stronger DNA binding affinities.

Composite Ferroelectric Coatings Based on a Heat-Resistant Polybenzoxazole Polymer Matrix

The polycondensation of 5,5 -methylene bis(2-aminophenol) and the mixture of diamines 5,5 -methylene bis(2-aminophenol) and 4,4-(hexafluoroisopropylidene)dianiline (molar ratio 0.8:0.2) with isophthaloyl dichloride was used to synthesize a new heat resistant binder of the composites for microelectronics: poly(o-hydroxyamide) (POA) and poly(amido-o-hydroxy amide) (POA-F). The thermal stability of synthesized polymer coatings, as well as based on them photosensitive compositions with a naphthoquinondiazide photosensitive component were studied in the temperature range from 100 to 500 degrees C. Ferroelectric composites with nanodispersed lead titanate zirconate powder filler were formed based on these polymer matrices. By manipulating the conditions of the polymer formation, we obtained matrices with different stiffnesses, which reflected on the properties of the composite. The electrophysical parameters of the synthesized polymer and ferroelectric composite coatings were measured in the frequency range from 0.1 Hz to 1.5 GHz and the temperature range from 0 to 300 degrees C. The frequency and temperature stability of the dielectric constant of ferroelectric composite coatings up to 10 MHz and 300 degrees C, respectively, are noted. The influence of the composition and structure of the polymer matrix and the grain/matrix interfaces on the thermal stability of the dielectric parameters of composite films is estimated. The shift of the phase transition region toward higher temperatures in the composite structure, as well as the sufficient rigidity of the poly(benzoxazole) matrix, provide high temperature and frequency stability of the dielectric constant of the studied composites.
