Derivatives based on anthryleno[1,2-b]pyrazine-2,3-dicarbonitrile (DCPA) are used as luminescent materials, to realize near-infrared (NIR) electroluminescence. By functionalizing DCPA with aromatic amine donors, two emitters named DCPA-TPA and DCPA-BBPA are designed and synthesized. Both molecules have large dipole moments owing to the strong intramolecular charge transfer interactions between the amine donors and the DCPA acceptor. Thus, compared with doped films, the emission of neat films of DCPA-TPA and DCPA-BBPA can fully fall into the NIR region (>700 nm) with increasing surrounding polarity by increasing doping ratio. Moreover, the non-doped devices based on DCPA-TPA and DCPA-BBPA provide NIR emission with peaks at 838 and 916 nm, respectively. A maximum radiance of 20707 mW Sr-1 m(-2) was realized for the further optimized device based on DCPA-TPA. This work provides a simple and efficient strategy of molecular design for developing NIR emitting materials.

Functionalized Tetrapodal Diazatriptycenes for Electrostatic Dipole Engineering in n-Type Organic Thin Film Transistors

A diazatriptycene-based tetrapodal scaffold with thiol anchors enforces a nearly upright orientation of functional groups, introduced to its quinoxaline subunit, with respect to the substrate upon formation of self-assembled monolayers (SAMs). Substitution with electron-withdrawing fluorine and cyano as well as electron-rich dimethylamino substituents allows tuning of the molecular dipole and, consequently, of the work function of gold over a range of 1.0 eV (from 3.9 to 4.9 eV). The properties of the SAMs are comprehensively investigated by infrared reflection absorption spectroscopy, near edge X-ray absorption fine structure spectroscopy, and X-ray photoelectron spectroscopy. As prototypical examples for the high potential of the presented SAMs in devices, organic thin-film transistors are fabricated.

Clean Grinding Technique: A Facile Synthesis and In Silico Antiviral Activity of Hydrazones, Pyrazoles, and Pyrazines Bearing Thiazole Moiety against SARS-CoV-2 Main Protease (M-pro)

A novel series of some hydrazones bearing thiazole moiety were generated via solvent-drop grinding of thiazole carbohydrazide 2 with various carbonyl compounds. Also, dehydrative-cyclocondensation of 2 with active methylene compounds or anhydrides gave the respective pyarzole or pyrazine derivatives. The structures of the newly synthesized compounds were established based on spectroscopic evidences and their alternative syntheses. Additionally, the anti-viral activity of all the products was tested against SARS-CoV-2 main protease (M-pro) using molecular docking combined with molecular dynamics simulation (MDS). The average binding affinities of the compounds 3a, 3b, and 3c (-8.1 +/- 0.33 kcal/mol, -8.0 +/- 0.35 kcal/mol, and -8.2 +/- 0.21 kcal/mol, respectively) are better than that of the positive control Nelfinavir (-6.9 +/- 0.51 kcal/mol). This shows the possibility of these three compounds to effectively bind to SARS-CoV-2 Mpro and hence, contradict the virus lifecycle.

Creation of novel alleles of fragrance gene OsBADH2 in rice through CRISPR/Cas9 mediated gene editing

Fragrance in rice grains is a key quality trait determining its acceptability and marketability. Intensive research on rice aroma identified mutations inbetaine aldehyde dehydrogenase(OsBADH2) leading to production of aroma in rice. Gene editing technologies like CRISPR/Cas9 system has opened new avenues for accelerated improvement of rice grain quality through targeted mutagenesis. In this study, we have employed CRISPR/Cas9 tool to create novel alleles ofOsBADH2leading to introduction of aroma into an elite non-aromatic rice variety ASD16. PCR analysis of putative transformants using primers targeting the flanking regions of sgRNA in the 7(th)exon ofOsBADH2identified 37.5% potential multi-allelic mutations in T(0)generation. Sensory evaluation test in the leaves of T(0)lines identified thirteen lines belonging to five independent events producing aroma. Sequence analysis of these aromatic T(0)lines identified 22 different types of mutations located within -17 bp to +15bp of sgRNA region. The -1/-2 bp deletion in the line # 8-19 and -8/-5 bp deletion in the line # 2-16 produced strong aroma and the phenotype was stably inherited in the T(1)generation. Comparative volatile profiling detected novel aromatic compounds viz., pyrrolidine, pyridine, pyrazine, pyradazine and pyrozole in the grains of T(1)progenies of line # 8-19. This study has demonstrated the use of CRISPR/Cas9 in creating novel alleles ofOsBADH2to introduce aroma into any non-aromatic rice varieties.

A domino annulation approach to 3,4-diacylpyrrolo[1,2-a]pyrazines: decoration of pyrazine units

A new one-pot, sequential three-component access to 3,4-diacylpyrrolo[1,2-a]pyrazine was achieved from the reaction of an alpha-haloketone, azide, and N-substituted pyrrole-2-carboxaldehyde under mild reaction conditions, through which a polysubstitution pattern on the pyrazine moiety of the scaffold was realized. The formation of multiple bonds (one C-C and two C-N) was enabled by this domino process involving the in situ generation of alpha-iminoketones, intermolecular Mannich reaction, intramolecular imine formation, and aromatization. Construction of the relevant 3,4-diacylpyrazino[1,2-a]indole and further expansion of this chemical space via synthetic elaboration of the resulting products were demonstrated as well. Preliminary biological screening of the synthesized derivatives against oral adenosquamous carcinoma cells (CAL-27) and triple negative human breast cancer cells (MDA-MB-231) led us to identify a potent hit compound (7o) having similar to 3 times stronger in vitro anticancer activity than that of the anticancer agent, capecitabine.

Electron-Rich, Lewis Acidic Diborane Meets N-Heterocyclic Aromatics: Formation and Electron Transfer in Cyclophane Boranes

Herein reported are the reactions of an electron-rich, Lewis acidic diborane with N-heterocyclic aromatics to give first members of an unprecedented family of highly charged cationic cyclophanes with diboranyl units. Tetracationic cyclophanes with 4,4′-bipyridine/ 1,2-bis(4-pyridyl)ethylene and diboranyl units were synthesized and their redox chemistry was studied. Cyclisation of two diboranyl and two pyrazine units is accompanied by electron transfer from the diboranyl unit to the pyrazine. Our results pave the way for the integration of redox-active diboranyl units into cyclophanes and supramolecular structures.

Suppressing dimer formation by increasing conformational freedom in multi-carbazole thermally activated delayed fluorescence emitters

Ideal emitters for organic light-emitting diodes (OLEDs) are capable of efficiently harvesting non-emissive triplet states, have high colour stabilities, and possess high photoluminescence quantum yields (PLQYs). Maintaining colour stability and PLQY is particularly challenging for multi-carbazole thermally activated delayed fluorescence (TADF) materials that form persistent dimers due to intermolecular interactions of their extended aromatic systems (with altered electronic states). Addressing this challenge, three new emitters are presented, which demonstrate that, somewhat counterintuitively, sterically uncrowded acceptor units can suppress these undesirable interactions. They do so by allowing the surrounding carbazole donors to be arranged with lower dihedral angles, which in turn limits their availability for dimerization. A new pyrazine-centered emitter 4CzPyz is contrasted directly with the cyanopyridine and terephthalonitrile analogues, 4CzCNPy and 4CzTPN respectively. The pyrazine derivative demonstrates enhanced colour stability in the solid-state compared to the cyanopyridine and terephthalonitrile acceptors, which we assign to its absence of intermolecular face-to-face aromatic interactions. This suppression of dimer formation is shared by two cyanopyrazine emitters 2Cz2CNPyz and 3CzCNPyz, each of which feature reduced steric pressure and flatter Cz-Pyz dihedral angles than non-heterocyclic analogues. Flatter dihedral angles consequently lead to C-H bonds of the Cz donors extending outwards at angles that prevent the stacking required for dimerization. This expanded understanding of dimer formation in TADF materials will guide future efforts to maintain colour stability in higher performance TADF materials by curbing the prevalence of face-to-face aromatic interactions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 2847-30-5. Formula: C6H8N2O.

Coordination polymers based on 3,5-di-tert-butylbenzoate {Cd2Eu} moieties

Heterometallic complex [Cd2Eu(bzo)(6)(NO3)(MeCN)(2)(THF)(2)]center dot 2EtOH was synthesized by the reaction of Cd (NO3)(2)4H(2)O and Eu(NO3)(3)6H(2)O with potassium 3,5-di-tert-butylbenzoate (Hbzo). N-Donors (L) could replace solvents in the Cd coordination environment without modifying the stable metal core {Cd2Eu(bzo)(6)(X)} (X = NO3 or bzo). The presence of pyrazine (pz) in the reaction mixture could result in the formation of either molecular [Cd2Eu(bzo)(6)(NO3)(pz)(2)(EtOH)(2)] or 1D-polymeric [Cd2Eu(bzo)(6)(NO3)(pz)(H2O)(2)]ncomplex, depending on the Cd : L molar ratio (1 : 15 and 1 : 8, respectively). Addition of bridging N-donors 4,4′-bipyridine (4,4′-bipy) and 1,2-bis(2-pyridyl)ethylene (bpe) (Cd : L = 1 : 2) gave the [Cd2Eu(bzo)7(4,4′-bipy)(H2O)(2)](n) and [Cd2Eu(bzo)(7)(bpe)(H2O)(2)](n) polymers, respectively. 4-Methyl-2-aminopyridine (ampy) gave only molecular compound [Cd2Eu(bzo)(7)(ampy)(2)(EtOH)(H2O)] (Cd : L = 1 : 3). The structures of all the resulting compounds were studied by single crystal X-ray diffraction analysis. Photoluminescent properties were studied for solid samples of the synthesized compounds. The effect of the N-donor ligand geometry and the Eu center dot center dot center dot Eu distance on the lifetime of the Eu3+ atom’s D-5(0) excited state is discussed.
