A crown-ether appended N-heteroacene 1 was reduced in the presence of NaBPh4 to the radical anion 2 by accepting one electron transferred from both the cathode and BPh4- as a reductant. The obtained radical anion 2 can function as a radical anion ligand to bridge two sodium ions to self-assemble into one-dimensional helical coordination polymers.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Studies on herbicidal 2,3-dicyanopyrazines. Part III. Structure-activity relationship in herbicidal activity of 5-chloro-2,3-dicyanopyrazines against barnyardgrass (Echinochloa curs-galli), published in 1983-12-31, which mentions a compound: 56413-95-7, Name is 5,6-Dichloropyrazine-2,3-dicarbonitrile, Molecular C6Cl2N4, Reference of 5,6-Dichloropyrazine-2,3-dicarbonitrile.

The herbicidal activities of 6-substituted 2,3-dicyano-5-chloropyrazines were evaluated and correlated with the previously reported substituent parameters π (hydrophobicity) and σp (Hansch, A., et al., 1973). Parameters π and π2 indicate that the hydrophobicity of the mol. is involved in the translocation of these compounds to the target site. The activity decreases with increasing electron-withdrawing property of the 6-substituent. The herbicidal activity varied parabolically with the change in π.

Phthalocyanines (Pc) and their aza-analogs azaphthalocyanines (AzaPc) (tetrapyrazinoporphyrazines) with eight n-octylsulfanyl or tert-butylsulfanyl peripheral substituents and different central metals (Mg, Zn, metal-free) were synthesized. Dimerization constants Kd and absorption spectra of pure monomeric and dimeric magnesium complexes in toluene were calculated using series of absorbances at different concentrations The bulky tert-butylsulfanyl substituents were found to be much better inhibitors of aggregation than long alkyl chains. Also Pc are less aggregated in organic solvents then AzaPc, short explanation is given. Singlet oxygen production of Pc and AzaPc was compared using dye-sensitized photooxidation of 1,3-diphenylisobenzofuran in pyridine. Both Pc and AzaPc showed similar activity not dependent on type of peripheral substitution. Zinc complexes of both Pc and AzaPc exceeded the magnesium ones and metal-free dyes in singlet oxygen production approx. twice.

Lindqvist polyoxometalate (POM) additives increase VOC in p-type DSSCs by up to 140%, yielding substantial efficiency gains for poorly matched dyes and redox mediators. For better dye/electrolyte combinations, these gains are typically outweighed by losses in JSC. Charge lifetime and transient IR measurements show that this is due to retardation of both recombination and electron transfer to the mediator, and a pos. shift in the NiO valence band edge. The POMs also show their own, limited sensitizing effect.

There is still a lot of research devoted to this compound(SMILES：N[C@H]1CC[C@H](CC1)C(O)=O)SDS of cas: 3685-23-2, and with the development of science, more effects of this compound(3685-23-2) can be discovered.

Category: chiral-oxygen-ligands. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile, is researched, Molecular C6Cl2N4, CAS is 56413-95-7, about Low-Power Laser Ignition of an Antenna-Type Secondary Energetic Copper Complex: Synthesis, Characterization, Evaluation, and Ignition Mechanism Studies.

In recent years, development of new energetic compounds and formulations, suitable for ignition with relatively low-power lasers, is a highly active and competitive field of research. The main goal of these efforts is focused on achieving and providing much safer solutions for various detonator and initiator systems. In this work, a new laser-ignitable compound, based on the 5,6-bis(ethylnitroamino)-N′2,N′3-dihydroxypyrazine-2,3-bis(carboximidamide) (DS3) proligand is prepared, characterized, and thermal and ignition properties are studied. This new energetic proligand was prepared in three steps, starting with 5,6-bis(ethylamino)-pyrazine-2,3-dicarbonitrile. Crystallog. studies of the DS3-derived Cu(II) complex (DS4) revealed a unique stacked antenna-type structure of the latter compound DS4 has an exothermal temperature of 154.5° and was calculated to exhibit a velocity of detonation of 6.36 km·s-1 and a detonation pressure of 15.21 GPa. DS4 showed properties of a secondary explosive, having sensitivity to impact, friction, and electrostatic discharge of 8 J, 360 N, and 12 mJ, resp. In order to study the mechanism of ignition by a laser (using a diode laser, 915 nm), a set of experiments are conducted that enabled to characterize a photothermal ignition mechanism. Furthermore, it was found that a single pulse, with a time duration of 1 ms and with a total energy of 4.6 mJ, was sufficient for achieving a consistent and full ignition of DS4. Dual-pulse experiments, with variable time intervals between the laser pulses, showed that DS4 undergoes ignition via a photothermal mechanism. Finally, calculating the chem. mechanism of the formation of the complex DS4 and modeling its anhydrous and hydrated crystal structures (d. functional theory calculations using Gaussian and HASEM software) allowed to pinpoint a more precise location of water mols. in exptl. crystallog. data. These results suggest that DS4 has potential for further development to a higher technol. readiness level and for integration into small-size safe detonator systems as for many civil, aerospace, and defense applications.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: cis-4-Aminocyclohexane carboxylic acid, is researched, Molecular C7H13NO2, CAS is 3685-23-2, about Investigating the Stability of Double Head to Tail Dimers and Ribbons in Multicomponent Crystals of cis-4-Aminocyclohexanecarboxylic Acid with Water and Oxalic Acid.Computed Properties of C7H13NO2.

The current contribution aims to study the stability of commonly occurring motifs present in certain amino acid structures after introducing addnl. mols. to form multicomponent crystals. The crystal structures of the amino acid cis-4-aminocyclohexanecarboxylic acid hemihydrate I and dehydrate II forms and that of its oxalate salt cocrystd. with oxalic acid III, were studied employing a combination of techniques. Both single-crystal and powder x-ray diffraction were used to solve the structures, while temperature-control powder X-ray diffraction was used to follow the dehydration of I. Regardless of the added mols. that induce modifications of the intermol. interactions within the crystals, some recurring supramol. structures were identified: double head to tail dimers, graph symbol R22(16), and ribbons, graph symbol R22(16)R34(10). Stabilities of these supramol. motifs were studied using theor. modeling with DFT/B3LYP/6-31++G (d,p) and PM6-D2H calculations The theor. calculations reproduced the exptl. findings, confirming the extraordinary stability of these motifs. The mol. recognition of amino acid pairs to form double head to tail-dimers is undoubtedly the initial driving force for the crystal formation in all the three crystals studied.
