4-Hydrazinylidene-1-methyl-3<i>H</i>-2λ⁶,1-benzothiazine-2,2-dione

In the title compound, C(9)H(11)N(3)O(2)S, the thia-zine ring adopts a half-chair conformation. In the crystal structure N-H⋯N hydrogen bonds connect two mol-ecules into a centrosymmetric dimer, forming an R(2) (2)(6) ring motif. These dimers are further connected into chains by N-H⋯O and C-H⋯O hydrogen bonds.

4-(3-Methyl-5-phenyl-1<i>H</i>-pyrazol-1-yl)benzenesulfonamide

With respect to the planar five-membered ring of the title compound, C(16)H(15)N(3)O(2)S, the phenyl ring is aligned at 47.0 (1)° and the phenyl-ene ring at 37.6 (1)°. The amino group has the N atom in a pyramidal geometry; the group is a hydrogen-bond donor to the sulfonyl O atom of one mol-ecule and to the pyrazole N atom of another mol-ecule, resulting in the formation of a layer parallel to the bc plane.

Synthesis of Taurine-Containing Peptides, Sulfonopeptides, and <i>N</i>- and <i>O</i>-Conjugates

Taurine-containing water-soluble peptidomimetics were designed and synthesized. N-terminal taurine acylations allowed synthesis of a number of taurine-containing peptides. N-protection of taurine with Cbz and SO2-activation with benzotriazole followed by coupling with various amino esters, dipeptides and nucleophiles provided taurine N- and O-conjugates and sulfonopeptides.

2E,2'E-3,3'-(1,4-Phenylene)bis(1-(2,5-dimethylfuran-3-yl)prop-2-en-1-one

A bis-chalcone has been synthesized by reaction of 3-acetyl-2,5-dimethylfuran and terephthalaldehyde in ethanolic NaOH at room temperature: (2E,2'E)-3,3'-(1,4-phenylene)bis(1-(2,5-dimethylfuran-3-yl)prop-2-en-1-one) (3) was obtained in high yield. The structure of this compound was established by elemental analysis, IR, 1H NMR, 13C NMR and EI-MS spectral analysis.

A MoN nanosheet array supported on carbon cloth as an efficient electrochemical sensor for nitrite detection

Nitrite, widely found in the environment and the food industry, poses a great threat to human health because of its potential toxicity, and its detection is highly important. We report that a MoN nanosheet array on carbon cloth (MoN NA/CC) behaves as an efficient catalyst for nitrite reduction in neutral solution. As a nitrite sensor, this MoN NA/CC offers a wide linear range from 1 μM to 5 mM and a low detection limit of 3 nM (S/N = 3), with a high sensitivity of 4319 μA mM^-1 cm^-2 and long-term stability and reproducibility.

(2<i>E</i>)-2-(Furan-2-ylmethylidene)-2,3-dihydro-1<i>H</i>-inden-1-one

In the title compound, C(14)H(10)O(2), the five-membered ring of the inden-1-one residue is almost planar (r.m.s. deviation = 0.035 Å). A twist about the single bond linking the two residues is evident [C-C-C-C torsion angle = -13.2 (5)°]. The three-dimensional architecture is stabilized by C-H⋯O (involving the trifurcated carbonyl O atom), C-H⋯π and π-π inter-actions [between the five- and six-membered rings of inden-1-one residues; ring centroid-centroid distance = 3.7983 (17) Å]. The sample studied was a non-merohedral twin; the minor component refined to approximately 36%.

Comparative Study of the Structural, Electronic and Charge Transport Properties of Benzothiazole- and Indole-Based Squaraine Sensitizers

The donor organic sensitizers and acceptor inorganic part (e.g. TiO2 nanoparticles) gained significant attention in the field of photo-excitation, electrochemistry and hetero-junction solar cells. In the present study structural, electronic and charge transport parameters have been calculated with respected to benzothiazole- and indole-based squaraine dyes as donor while Si/TiO2 as acceptor then compared with previously studied hetero-junction solar cell materials. We have optimized the ground state geometries of benzothiazole- and indole-based squaraine dyes by density functional theory (DFT). The geometries of neutral, cation and anion species have been optimized by restricted and unrestricted B3LYP/6-31G** level of theories, respectively. The 2-3-(2-ethoxy-2- oxoethyl)benzo[d]thiazol-2(3H)-ylidene)methyl)-4-((3-(2-ethoxy-2-oxoethyl)benzo[d]-thiazol-3-ium-2-yl)methyl-ene)-3-oxocyclobut-1-enolate (BTSQD1) has been synthesized by our group. Moreover, we have designed derivatives of the benzothiazole-(BTSQD2 and BTSQD3 which have –COOH and –OCH3 at terminal –R positions, respectively) and indole-based squaraine dyes (ISQD1-ISQD3). The structures of the benzothiazole- and indole-based dyes investigated here are same except that in later ones the “sulfur” has been substituted by -C(CH3)2. We have compared the geometries, electronic properties, ionization potentials, electron affinities, reorganization energies, relationship between the energies of highest occupied molecular orbitals/lowest unoccupied molecular orbitals and open-circuit voltages (Voc), diagonal band gaps and short circuit current densities (Jsc), fill factors (FF) and factors affecting on the external quantum efficiency.
