To explore the influence of various anions on the self-assembly and properties of silver complexes, reactions of anions of silver salts with 2,2 ‘-(1,4-butanediyl)bis-1,3-benzoxazole (BBO) afforded four complexes, formulated as [Ag-2(BBO)(2)(p-toluenesulfonate)(2)] (1), {[Ag(BBO)(picrate)]}(infinity) (2), {[Ag(BBO)(1/2)(o-coumarate)]center dot DMF}(infinity) (3) and {[Ag-2(BBO)(3)](PF6)(2)}(infinity) (4). These complexes were characterized using elemental analysis, infrared spectroscopy and single-crystal X-ray diffraction. The crystal analysis results show that under the influence of coordination modes and steric hindrance of anions, the complexes exhibited binuclear (1), one-dimensional polymeric (2 and 3) and two-dimensional polymeric (4) structures. Compared with the BBO ligand, only complex 1 has a new emission peak at 428 nm, which is attributed to ligand-metal charge transfer. The emission peaks of complexes 2-4 are similar to those of the BBO ligand, which can be due to pi-pi* and n-pi* transitions. These results indicate that anions can modulate the structures and luminescent properties of silver complexes. Moreover, cyclic voltammograms of 1-4 indicated an irreversible Ag+/Ag couple with the order of reversibility being 2 > 1 > 4 > 3. In vitro antioxidant experiments showed that complex 3 has significant antioxidant activity against superoxide and hydroxyl radicals.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

When, cyanothioformamide derivatives are reacted with certain electrophiles, they produce imidazole, oxazole, thiazole, 2,5-thiadiazole, bis-imidazole and bis-oxazole derivatives; while the reaction with certain nucleophiles furnish benzoxazole, quinaolinone, triazole, bis-triazole, benzoxazinethione and 1,3,4-thiadiazole derivatives. Imidazolidineiminothione derivatives were obtained by ring closure reaction of cyanothioformamide derivatives with isocyanates. These reactions give rise to imidazole derivatives that contain adjacent thione and imino functional groups in the positions 4 and 5 which are reactive in numbers of subsequent ring closure reactions. These compounds find applications as medicinal and pharmacological agents.

A novel highly thermal stable propargyl functional compound containing benzoxazole ring, N, N, N, N-tetra propargyl-5-amino-2-(p-aminophenyl) benzoxazole (TPAPB), was proposed and synthesized using a phase-transfer catalytic method. The cure behavior of TPAPB was investigated by non-isothermal differential scanning calorimetry analysis. The solubility and rheological properties of TPAPB, as well as its broad temperature window from 130 degrees C to 200 degrees C with low viscosity, offered excellent processability for TPAPB to be used as a potential monomer of thermosetting polymer resin. It was found that the glass transition temperature of cured TPAPB was 359 degrees C, and the temperature of 5% weight loss was 418 degrees C in argon with the char residue up to 70% at 700 degrees C. The polymerized resin exhibited high heat resistance and thermal stability, together with its processability, making it good candidate as highly heat-resistant polymer matrix for advanced composite applications.

Now introduce a scientific discovery about this category.

A series of poly(hyroxyamide)s (PHAs) was prepared by direct polycondensation reaction of 4,4′-(2,3-pyridinedioxy)dibenzoic acid and/or isophthalic acid with 3,3′-dihydroxybenzidine. The yield percentages of the products were high, and the inherent viscosities of the polymer in DMAc solution at 35 degrees C were 0.31-0.59 dL/g. All PHA polymers were found to be soluble in polar aprotic solvents such as DMAc, DMSO, NMP, and DMF. On the other hand, LiCl was required to dissolve IPHA-1 in aprotic solvents. Poly(benzoxazole)s (PBOs) were partially soluble in conc-H2SO4; IPBO-4, -5, and -6 were partially soluble in NMP only when LiCl was added to the solution, and the solution was heated. The PBO polymers showed a maximum weight loss in the temperature range of 654-680 degrees C, and the char yields at 900 degrees C under nitrogen atmosphere exceeded 63%.
