Rational design of diketopyrrolopyrrole-based multifunctional materials for organic light-emitting diodes and organic solar cells

A series of donor-acceptor diketopyrrolopyrrole derivatives has been investigated to reveal their optical, electronic, and charge transport properties for applications in organic light-emitting diodes (OLEDs) and organic solar cells (OSCs). The calculated results show that their optical, electronic, and charge transport properties are affected by the different end groups. The introduction of the 2,5-diphenylthiophene, benzo[c]isothiazole, benzo[c]thiophene, benzo[c]thiophene, 2,4-dihydrobenzo[d]thiazole, and thieno[3,4-b][1,4] dioxine end groups can broaden absorption spectrum and improve charge transport property of the designed compounds. Our results suggest that the designed compounds can serve as donor materials for OSCs and luminescent materials for OLEDs. In addition, the mobility of the designed compounds is also investigated. They are expected to be promising candidates for hole and electron transport materials. On the basis of investigated results, we proposed a rational way for the design of multifunctional materials for OLED and OSC applications.

Morphological study of Trichophyton rubrum: ultrastructural findings after treatment with 4-amino-3-methyl-1-phenylpyrazolo-(3,4-c)isothiazole

The antifungal activity of 4-amino-3-methyl-1 -phenylpyrazolo-(3,4-c)isothiazole was studied on Trichophyton rubrum. The compound, at concentrations between 20 and 100 mu g ml(-1), induces a remarkable reduction in the growth and causes deep morphogenetic anomalies. The ultrastructural modifications have demonstrated that the compound targets the cell membrane of the fungus, breaking down not only the endomembrane system, but also the ‘outer’ membrane, with consequent extrusion of materials in the medium. The results suggests a mechanism of action similar to other azoles clinically utilized.

CONDENSATION OF MUSCIMOL OR THIOMUSCIMOL WITH AMINOPYRIDAZINES YIELDS GABA-A ANTAGONISTS

Ten analogs of muscimol and thiomuscimol in which the amino function was delocalized in an amidinic system were prepared by N2 alkylation of 6-aryl-3-aminopyridazines with (chloromethyl) isoxazole or (chloromethyl)isothiazole derivatives. These muscimol and thiomuscimol derivatives show potent binding properties for GABA-A receptors (they displace [H-3]GABA and [H-3]gabazine) and provoke convulsions after iv injections. They fit well with the model pharmacophore proposed by our group for the GABA-A antagonists and show similar structure-activity profiles to that of the pyridazinyl-GABAs.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 6315-52-2, in my other articles.

Enolates of 2-Isothiocyanatocarboxylic Esters: Synthesis of Thiazolo[5,4-d]-thiazole Derivatives and 2-Thioxo-1,3-thiazolidine-4-carboxylates

An oxidative dimerization of titanium(IV) enolates derived from menthyl esters of 2-isothiocarboxylic acids leads to radical coupling followed by cyclization. This cascade reaction gives thiazolo[5,4-d]thiazole derivatives as pure enantiomers. Under similar conditions, 2-methylbutyl esters of 2-isothiocyanatocarboxylic acids undergo intermolecular oxidative dimerization to give mixtures of thiazolo[5,4-d]thiazoles and 2,3-diisothiocyanatosuccinates. Application of the soft enolization technique to dimethyl alpha,alpha’-diisothiocyanatodicarboxylic esters gives novel cyclic 1,2-diisothiocyanato-1,2-dicarboxylates. Sodium enolates of 2-isothiocyanatocarboxylates, on the other hand, form 5-imino-2-thioxo-1,3-thiazolidine-4-carboxylic esters by nonoxidative dimerization. The mechanisms of the two reaction pathways are discussed.

Synthesis and experimental versus theoretical research on spectroscopic and electronic properties of 3-methyl-4-nitroisothiazole

The alternative way of synthesis of valuable 5-amino-3-methylisothiazole and 3-methyl-4-nitroisothiazole has been presented and described. It appeared that new, undescribed 3,3′-dimethyl-4,4′-dinitro-5,5′-bisisothiazole has been produced as a side-product during synthesis. Both experimental and calculated spectral and electronic properties of 3-methyl-4-nitroisothiazole have been extensively researched and discussed. The complete vibrational assignments were made on the basis of potential energy distributions PED. The fully anharmonic infrared and Raman spectra with calculated anharmonic intensities for fundamental bands, overtones as well as combination bands are presented. Vibrational spectra predicted by anharmonic approximation agree very well with experimental data. The stability of molecules of 3-methyl-4-nitroisothiazole arising from hyper conjugative interaction has been estimated using natural bond orbital (NBO 6.0) analysis. The combined frontier molecular orbital and NBO analysis of canonical molecular orbitals was used to predict the most probable sites of 3-methyl-4-nitroisothiazole molecule where single electron can be accepted to and detached from. Measured reduction potential of 3-methyl-4-nitroisothiazole and calculated electron affinity point out that this compound is susceptible to reduction at the similar level of 1-methyl-3-nitropyrazole and this susceptibility is much more than respective 1-methyl-4-nitropyrazole. UV-Vis spectra analysis reveals a nature of valence electron excitation and electron transition of 3-methyl-4-nitroisothiazole. Besides, unambiguous assignment of NMR signal shifts of carbon atoms of isothiazole ring of 3-methyl-4-nitroisothiazole, 5-amino-3-methylisothiazole and intermediate and side products of synthesis was conducted thanks to full detailed analysis of H-1, C-13 NMR spectra and their two dimensional (2D) variants. Additionally, molar enthalpy of vaporization (Delta H-vap) of 3-methyl-4-nitroisothiazole has been estimated (Delta H-vap = 52.2 kJ/mol). (C) 2019 Elsevier B.V. All rights reserved.

CONDENSATION OF 5-AMINOISOTHIAZOLES WITH N-METHYL-IMIDOYL CHLORIDE – RING-TRANSFORMATION WITH PARTICIPATION OF 10-S-3-TYPE SULFURANE

In the presence of 1,4-diazabicyclo[2.2.2]octane, 5-amino-3-methylisothiazole (4a) in acetonitrile condensed with N-methyl-p-chlorobenzimidoyl chloride (5a) to afford two kinds of compounds along with several minor products. One of the two was 1 : 1 condensed product (6a) and the other was 2 : 1 condensed product (7a). The latter compound was obtained in higher yield when an excess 4a was treated with 5a. On the other hand, in the absence of the additional base, 2 : 3 condensed compound (8a) was isolated as a major product besides 6a and 7a. 8a was obtained by treatment of 7a with 2 equiv. of imidoyl chloride in 21% yield. Reaction of 5-amino-3-phenylisothiazole (4b) with imidoyl chloride (5a,b) furnished the analogous products. On the other hand, condensation of 5-amino-3-phenylisoxazole (4c) with 5a furnished the oxygen analogue (6d) corresponding to 6b as a sole isolated product. The formation of 7 is explained by ring-transformation from isothiazole into thiadiazole via hypervalent 10-S-3 type sulfurane (B). According to a variety of investigations of heterocycles containing sulfur atom, it has been suggested that 10-S-3 type sulfurane is an important intermediate in several reactions.1,2. In a previous paper, we reported that a ring transformed thiadiazole derivative (1) instead of the expected isothiazole derivative (2) was isolated as a sole product in the reaction of 5-amino-3-methylisothiazole with arylnitrile.3a The fact was explained by invoking 10-S-3 sulfurane (A) as a intermediate. In connection with this finding, we describe in this paper results of the reaction of 5-aminoisoazole derivatives (4a-c) with imidoyl chloride (5a,b) under several conditions.
