Method for manufacturing organic electronic devices

The present invention relates to a method for manufacturing organic electronic devices including a dipyrannylidene film as an anodic interface layer, the method being carried out in a vacuum and without any exposure to air. The invention also relates to o

Selective and sensitive chromofluorogenic detection of the sulfite anion in water using hydrophobic hybrid organic-inorganic silica nanoparticles

In water and wine: Chromofluorogenic detection of the sulfite anion in pure water was accomplished by using a new hybrid organic-inorganic material that contained a probe entrapped in hydrophobic biomimetic cavities. This material was used for the detecti

An instantaneous and highly selective chromofluorogenic chemodosimeter for fluoride anion detection in pure water

The fast and the fluoride: A pyridine derivative functionalized with ferf-butyl-dimethylsilyl ether has been synthesized and used as a selective chromofluoro-genic fluoride sensor in water/cetyltri-methylammonium bromide solutions. The chromofluorogenic r

Hg2+ and Cu2+ selective detection using a dual channel receptor based on thiopyrylium scaffoldings

2,4,6-Triphenylthiopyrylium functionalized with an aza-oxa-thia macrocycle is able to selectively recognize Hg2+ cation by a color change and Cu2+ cation by a remarkable significant emission enhancement.

The use of N,N-dialkyltrimethylsilylamines in the synthesis of pentamethinium salts

N,N-Dialkyltrimethylsilylamines were used for the synthesis of a series of pentamethinium salts starting from 2,6-disubstituted or 2,4,6-trisubstituted pyrylium salts, N-substituted 5-aminopenta-2,4-dienals or N-substituted 5-aminopenta-2,4-dien-1-ones. The reactions proceed smoothly under mild conditions, furnishing the desired products in good yields. Georg Thieme Verlag Stuttgart.

Reactions of 3-Thia(Selena)Pentane-1,5-Diones with Lewis Acids

3-Thia(selena)pentane-1,5-diones react with Lewis acids by hetero-atom. In these reactions soft Lewis acids such as tin tetrachloride and antimony pentachloride form adducts but hard Lewis acid such as phosphorus pentachloride oxidizes chalcogen atom of 3

Ethynyl Carbocations. V. Synthesis and Properties of 4-Phenylethynyl-4H-pyrans

A method for preparation of 4-phenylethynyl-4H-pyrans was developed, and their reactions with acid reagents, resulting in 4-phenylethynylpyrylium salts and 1,5-diketones containing ethynyl and allene moieties, were studied.Conditions for nucleophilic addi

Electrophilic Reactions of Carbonyl Compounds and their Derivatives. VI. Vinyl Ethers and Chlorinated Hydrocarbons in the Synthesis of Pyrylium Salts

Two- and three-component condensations of α-ethoxystyrene with carbonyl compounds and their derivatives serving as a source of heterocarbenium and hydroxyallyl cations are studied.The reactions result in formation of monocyclic pyrilium salts.

The Relative Electron Donating Ability of Substituents, Determined in 2,6-Disubstituted Pyrylium Cations

Tha carbon-13 NMR spectra of a series of 2,6-disubstituted pyrylium compounds have been investigated.The chemical shift of C(4) is a measure of the charge density in that position of the ring.The variation of the chemical shift with the change of substitu

THE FORMATION OF OPEN-CHAIN CARBOXONIUM AND CARBIMMONIUM IONS AND THEIR HETEROCYCLIZATION TO PYRYLIUM AND PYRIDINIUM CATIONS

During the action of an anhydrous solution of perchloric acid in alcohol on methyl aryl ketones in ethyl orthoformate open-chain carboxonium salts (derivatives of the 1,5-diaryl-2-pentene-1,5-dione) were formed instead of the 2,6-diarylpyrylium perchlorat
