Self-patterning processes originated by physical stimuli have been extensively documented in thin films, whereas spontaneous wrinkling phenomena due to chemical transformation processes are, to the best of our knowledge, unprecedented. Herein we report a case of spontaneous polymerization-driven surface nano-patterning (?500 nm) that develops in smooth thin solid films of 5,6-dihydroxyindole (DHI), a major precursor of eumelanin polymers, over a time scale of 30 to 60 days in air at room temperature. The phenomenon can be observed only above a critical film thickness of ?250 nm and it is affected by exposure to ammonia vapors causing acceleration of the oxidation process. The thickness-dependent onset of wrinkling can be attributed to non-homogeneous rates of oxidation through the film causing slow swelling/expansion of the inner layers followed by fast stiffening and cross-linking in the outer layer exposed to higher oxygen levels.

Novel, squarylium dyes containing 1-(alkylcarbamoylmethyl)-2,3,3-trimethyl- 3H-indolium groups were synthesized and their UV/Vis and fluorescence spectra, aggregation, photo-stability and association with bovine serum albumin were studied. The absorption and emission max wavelengths of the dyes in different solvents were in the range 619-653 nm. Compared to a typical ethyl squarylium dye, the introduction of alkylcarbamoylmethyl groups reduced aggregation and improved molar extinction coefficient, fluorescence quantum yield and photo-stability in water. Moreover, the fluorescence intensity of the dyes increased upon the addition of BSA in pH 7.0 phosphate buffer solution. An excellent linear relationship (r2 = 0.9982) was obtained between fluorescence intensity and bovine serum albumin concentration.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 244-76-8, name is 9H-Pyrido[2,3-b]indole, introducing its new discovery. Formula: C11H8N2

Two structural isomeric host materials, 9-(4-(dibenzo[b,d]thiophen-4-yl)phenyl)-9H-pyrido-[2,3-b]indole (pDBTCb) and 9-(3-(dibenzo[b,d]thiophen-4-yl)phenyl)-9H-pyrido-[2,3-b]indole (mDBTCb), were designed and synthesized, incorporating dibenzothiophene (DBT) and alpha-carboline moieties via phenyl linkages and their device performances of phosphorescent organic light-emitting diodes (PHOLEDs) were also investigated. The different linkages between DBT and alpha-carboline on central phenyl spacer play an important role in the structure-property correlations. Although their photophysical properties were similar regardless of different linkage positions, the bis[2-(4,6-difluorophenyl)pyridinato-C2,N](picolinato)iridium(III)-based blue device with mDBTCb, which adopted a meta-linkage showed a significantly higher maximum quantum efficiency of 19.8% as compared to its para-linkage analog, pDBTCb (16.2%). A high quantum efficiency of 19.8% and only ca. 10% reduction of quantum efficiency at 1000 cd/m2 were demonstrated from the blue PHOLEDs with the mDBTCb host material.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 244-76-8 is helpful to your research. Formula: C11H8N2

Ruthenium porphyrins (particularly [Ru(2,6-Cl2tpp)CO]; tpp = tetraphenylporphinato) and RuCl3 can act as oxidation and/or Lewis acid catalysts for direct C-3 alkylation of indoles, giving the desired products in high yields (up to 82% based on 60-95% substrate conversions). These ruthenium compounds catalyze oxidative coupling reactions of a wide variety of anilines and indoles bearing electron-withdrawing or electron-donating substituents with high regioselectivity when using tBuOOH as an oxidant, resulting in the alkylation of N-arylindoles to 3{[(N-aryl-N-alkyl)amino]methyl} indoles (yield: up to 82%, conversion: up to 95%) and the alkylation of N-alkyl or N-H indoles to 3-[p-(dialkylamino)benzyl]indoles (yield: up to 73%, conversion: up to 92%). A tentative reaction mechanism involving two pathways is proposed: an iminium ion intermediate may be generated by oxidation of an sp3 C-H bond of the alkylated aniline by an oxoruthenium species; this iminium ion could then either be trapped by an N-arylindole (pathway A) or converted to formaldehyde, allowing a subsequent three-component coupling reaction of the in situ generated formaldehyde with an N-alkylindole and an aniline in the presence of a Lewis acid catalyst (pathway B). The results of deuterium-labeling experiments are consistent with the alkylation of N-alkylindoles via pathway B. The relative reaction rates of [Ru(2,6-Cl 2tpp)CO] catalyzed oxidative coupling reactions of 4-X-substituted N,N-dimethylanilines with N-phenylindole (using tBuOOH as oxidant), determined through competition experiments, correlate linearly with the substituent constants o (R2=0.989), giving a rho value of -1.09. This rho value and the magnitudes of the intra- and intermolecular deuterium isotope effects (kH/kD) suggest that electron transfer most likely occurs during the initial stage of the oxidation of 4-X-substituted N,N-dimethylanilines. Ruthenium-catalyzed three-component reaction of N-alkyl N-H indoles, paraformaldehyde, and anilines gave 3-[p-(dialkylamino)benzyl] indoles in up to 82% yield (conversion: up to 95%).
