New banana shaped A?D?pi?D?A type organic dyes containing two anchoring groups for high performance dye-sensitized solar cells

Two new bent A?D?pi?D?A type organic dyes (MA-1 and MA-2) consisting of carbazole and phenothiazine moieties as electron donors with 2,1,3-benzothiadiazole as a pi-linker with two end-anchoring groups are designed, synthesized and tested in DSSCs. The photophysical and electrochemical properties of the dyes are investigated in detail. Incorporation of phenothiazine unit in MA-2 resulted in high HOMO level (0.62?V vs. NHE), with a red shift in absorption maxima and broadening of the absorption spectrum. Under standard global AM 1.5 solar conditions, the MA-2 sensitized solar cells exhibited a short circuit photocurrent density of 13.1?mA?cm?2, an open-circuit voltage of 0.73?V, a fill factor of 0.72, corresponding to an overall conversion efficiency of 6.87%. Such design and development of molecular dyes are useful for improving the overall efficiency of DSSCs.

Phenothiazine-based benzoxazole derivates exhibiting mechanochromic luminescence: The effect of a bromine atom

Two phenothiazine-based benzoxazole derivates (PVB and BPVB) were designed and synthesized, and their photophysical properties were studied and compared. The results showed that both compounds emitted strong fluorescence in solution and in the solid state. Their emission wavelengths were also strongly affected by solvent polarity, indicating intramolecular charge transfer (ICT) transitions. Interestingly, the two compounds exhibited different mechanochromism. The ground film of PVB without bromine atoms can self-cure and change into the original film within 15 min at room temperature. The fluorescence of the ground film for BPVB showed no changes for at least 2 weeks. Meanwhile, a higher contrast fluorescence change was observed for the solid film of BPVB with bromine atoms under grinding, although PVB and BPVB exhibited similar spectral red shifts after grinding. Based on the spectral results and single-crystal structures, a mechanochromic mechanism is given.

Potassium carbonate-mediated tandem C-S and C-N coupling reaction for the synthesis of phenothiazines under transition-metal-free and ligand-free conditions

An efficient potassium carbonate-mediated tandem C-S and C-N coupling reaction between N-(2-iodophenyl)acetamides and 2-halo-benzenethiols has been developed. This protocol affords a simple and efficient approach for the construction of phenothiazine derivatives without the need for addition of transition-metal catalyst or ligand for the first time. Furthermore, the reaction can be easily performed on a large scale.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, Reference of 3939-23-9, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about Reference of 3939-23-9

Spiro[pyrrol-benzopyran]-based probe with high asymmetry for chiroptical sensing: Via circular dichroism

This contribution describes an efficient approach to constructing chiral spiro[pyrrol-benzopyran] (SPP) scaffold with high asymmetry. By combining chiral SPP and the achiral sensing moiety phenothiazine, the target probe P showed unprecedented reaction-based chiroptical sensing towards hypochlorite with switching CD signals.

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.Computed Properties of C12H8BrNS, you can also check out more blogs aboutComputed Properties of C12H8BrNS

Selective inhibitors of monoamine oxidase. 4. SAR of tricyclic N- methylcarboxamides and congeners binding at the tricyclics’ hydrophilic binding site

Linear [6.6.6] tricyclic moieties whose center ring is made of two atoms of differing size (here primarily thioxanth-9-ones and phenoxathiins) monosubstituted meta to the sulfur by C(O)NHMe include potent and selective inhibitors of monoamine oxidase A. Similarities with effects on SAR of acylamide and of diazapentacyclic substitution on such rings, including positional variables, the requirement for monomethylation (primary and dialkylated amides are inactive and higher monoalkylated amides show little or no potency), and that sulfur is optimally in sulfone form, suggest that binding to the enzyme occurs similarly in each series. No significantly greater rise in blood pressure was found in rats given sufficient 8 to inhibit most brain and liver MAO A and then followed by oral tyramine than was found on administration of tyramine to controls. This is in contrast to a large blood pressure rise in rats pretreated with phenelzine followed by tyramine, and in accord with the belief that an inhibitor selective for MAO A which is reversibly bound to the enzyme and therefore displaced by any ingested tyramine will not lead to the ‘cheese effect’ (hypertension during treatment with MAO inhibitors usually caused by ingestion of foods containing tyramine).

Photochromic Radical Complexes That Show Heterolytic Bond Dissociation

Photochromic materials have been widely used in various research fields because of their variety of photoswitching properties based on various molecular frameworks and bond breaking processes, such as homolysis and heterolysis. However, while a number of photochromic molecular frameworks have been reported so far, there are few reports on photochromic molecular frameworks that show both homolysis and heterolysis depending on the substituents with high durability. The biradicals and zwitterions generated by homolysis and heterolysis have different physical and chemical properties and different potential applications. Therefore, the rational photochromic molecular design to control the bond dissociation in the excited state on demand expands the versatility for photoswitch materials beyond the conventional photochromic molecular frameworks. In this study, we synthesized novel photochromic molecules based on the framework of a radical-dissociation-type photochromic molecule: phenoxyl-imidazolyl radical complex (PIC). While the conventional PIC shows the photoinduced homolysis, the substitution of a strong electron-donating moiety to the phenoxyl moiety enables the bond dissociation process to be switched from homolysis to heterolysis. This study gives a strategy for controlling the bond dissociation process of the excited state of photochromic systems, and the strategy enables us to develop further novel radical and zwitterionic photoswitches.

13C Nuclear Magnetic Resonance of Some Derivatives of Phenothiazines, Pyridobenzothiazines and Phenoxazines

Natural abundance 13C NMR studies were carried out on a series of phenothiazines, pyridobenzothiazines and phenoxazines.Chemical shift assignments were made on the basis of models, coupling patterns and aromatic substituent affects.For most of the compounds studied, substituents influence only the carbon chemical shifts of the substituted carbocyclic ring, while the chemical shifts of the unsubstituted ring are essentially the same as those of the parent heterocyclic compound.However, the 10-acetyl and 4′-nitro-10-phenyl groups affect the chemical shifts of several of the carbon atoms in the phenothiazine nucleus.An explanation in terms of resonance interactions between these groups and the N-10 lone-pair electrons is presented.
