Novel highly efficient fluoroionophores with a peri-effect and strong electron-donating receptors: TICT-promoted PET and signaling response to transition metal cations with low background emission

Novel fluoroionophores with piperazine frameworks as receptors for transition metal cations have been designed with the aid of calculation and synthesized. They exhibited low background emission and highly efficient fluorescence enhancements upon complexation with different transition metal cations, which could be ascribed to the special contribution of the TICT-promoted PET processes caused by the peri-effect and strong electron-donating receptors.

Synthesis, Crystal Structure, and DFT Study of Two New Dinuclear Copper(I) Complexes Bearing Ar-BIAN Ligands Functionalized with NO2 Groups

Two new bis(aryl-imino)-acenaphthene, Ar-BIAN (Ar = 2,4,6-trimethylphenyl = mes) ligands, bearing the NO2 group in the naphthalene moiety of the iminoacenaphthene at para- (5-NO2) and meta- (4-NO2) position, of formulation

Structure-property relationships in conjugated donor-acceptor systems functionalized with tetrathiafulvalene

The properties of two donor-acceptor compounds tetrathiafulvalene- acenaphtho[1,2-b] quinoxaline (1) and tetrathiafulvalene-3-nitro-acenaphtho[1,2- b]quinoxaline (2) have been investigated by solution-state studies (electrochemistry, absorption, self-assembly) and theoretical calculations (DFT, TD-DFT). The electrochemical studies indicate the nitro-substituted effect on their redox properties is negligible. Both compounds show effective intramolecular charge transfer (ICT) transitions in the UV-Visible range in solution. Compared with compound 1, compound 2 has a bathochromic shift in the absorption spectra, the λmax-ICT has been extended from 20800 cm-1 to 19700 cm-1 (480 nm to 507 nm). In addition, when the nitro group is employed, the self-assembly characteristics of the two compounds are substantially changed from ribbon-like nanostructures to root-like nanostructures. Density functional theory (DFT) calculations provide insights into their molecular geometries, electronic structures, and physico-chemical properties.

Substituent effects on the decomposition of chemiluminescent tricyclic aromatic dioxetanes

Three tricyclic 1,2-dioxetane derivatives, 1a, 2a and 3a were synthesized from their corresponding 1,4-dioxin acenaphthylene compounds, 1, 2 and 3, by reaction with singlet-oxygen (1O2) in dichloromethane. Evidence for the formation

Preparation of chiral trans-5-substituted-acenaphthene-1,2-diols by baker's yeast-mediated reduction of 5-substituted-acenaphthylene-1,2-diones

A series of trans-5-substituted-acenaphthene-1,2-diols were obtained in 21-72% yield with 97-100% ee by baker's yeast-mediated reduction of the corresponding acenaphthylene-1,2-diones, in the presence of DMSO as a co-solvent and under vigorous agitation.

A Convenient One-Pot Synthesis of Acenaphthenequinones from 1-Acenaphthenones by NBS-DMSO Oxidation

Acenaphthenequinone was obtained in 95percent yield whwn the teaction of 1-acenaphthenone with N-bromosuccinimide was carried uot in dimethyl sulfoxide at room temperature.Under similar conditions, several acenaphthenequinones were prepared from the corresponding 1-acenaphthenones in good yield.

Chemistry of Diazoacenaphthenones and Diazoacenaphthenes

Wolff rearrangements do not occur in photolyses or thermolyses of diazoacenaphthenone (1), 2-diazo-5-nitroacenaphthenone (2), and 2-diazoaceanthrenone (3) in various environments.Thermal and photochemical decompositions of 1 in cyclooctane result in loss of nitrogen and formation of 2-cyclooctylacenaphthenone (29).In 2-propanol containing oxygen, 1 converts photolytically to acenaphthenone (22), acetone (23), and 1,8-naphthalic anhydride (25).Irradiation of 1 in tert-butyl alcohol/oxygen yields 2-tert-butoxyacenaphthenone (28) by solvent capture along with 25.Diazoketones 1-3 do not effect photochemical cyclopropanation of simple olefins; electronegatively substituted olefins such as acrylonitrile and methyl acrylate do give spirocyclopropanes however.Oxazoles are formed by 1,3-dipolar reactions of 1-3 with nitriles with loss of nitrogen.Acetylenes also react photolytically with 1-3 with nitrogen expulsion to yield furanes regiospecifically.Thermolyses of 1-3 in acetylenes, however, result in initial 1,3-dipolar addition reactions to give spiropyrazoles which undergo spotaneous sigmatropic migrations of their carbonyl groups to nitrogen to form isoquinolines.Diazoacenaphthene (13) decomposes carbenically to acenaphthylene (66).Similarly, 2-diazo-1,1-dimethylacenaphthene (14) converts to 8-methylcyclopropacenaphthylene (66) which then isomerizes thermally to methylphenalenes (70a-d).Further, 2-diazoacenaphthenone ethylene acetal (17) thermolyzes and photolyzes with migration of one of its acetal oxygen moieties to yield 8,9-dihydroacenaphtho-p-dioxin (73).Ring contraction does not occur in carbenic decompositions of 13, 14, and 17.
