Literature survey revealed that a good number of anthracene and substituted anthracences are potential lasing organic compounds. As per Mitsuo Maeda 9,10 dimethyl and 9,10 diphenyl anthracenes exhibit lasing properties around, 435-450nm. In continuation of our studies27 it was proposed to synthesize new lasing organic dyes in particular, new anthracene derivatives and study their photophysical ...

A new approach for the investigation of a higher-order reaction by on-column reaction gas chromatography is presented. The reaction and the analytical separation are combined in a single experiment to investigate the Diels-Alder reaction of benzenediazonium-2-carboxylate as a benzyne precursor with various anthracene derivatives, i.e. anthracene, 9-bromoanthracene, 9-anthracenecarboxaldehyde an...

A family of heavy atom-free BODIPY-anthracene dyads (BADs) exhibiting triplet excited state formation from charge-transfer states is reported. Four types of BODIPY scaffolds, different in the alkyl substitution pattern, and four anthracene derivatives have been used to access BADs. Fluorescence and intersystem crossing (ISC) in these dyads depend on donor-acceptor couplings and can be accuratel...

The metabolism of benzo[a]pyrene (BP) is known to lead to a large number of oxygenated compounds, some of which can bind covalently to DNA. We have studied the integrated metabolism of BP in vivo in germ-free rats given (14)C-labeled BP. Urinary metabolites were separated into groups according to acidity using lipophilic ion exchangers. The groups were analyzed by mass spectrometry and were fur...

Rainbow trout were exposed for 72 h to [ 14C]anthracene alone and [ I4C]anthracene in an oil shale retort water. Tissue levels of [I4C]anthracene were analyzed at 24, 48 and 72 h to determine non-steady-state bicconcentration factors (BCFs), and uptake and depuration rates were calculated from anthracene disappearance in exposure waters and metabolite appearance in depuration waters. Uptake rat...

Electroluminescent 9,10-diaryl anthracenes have been shown to be promising host and hole-transporting materials in organic electroluminescence due to their high thermal stability, electrochemical reversibility, and wide band gap useful for organic light-emitting diodes (OLEDs), especially blue OLEDs. Oxidation of cyclotriveratrylene (CTV) to the corresponding diketone and subsequent bromination...

Azonafide (2-[2'-(dimethylamino)ethyl]-1,2-dihydro-3H-dibenz[de, h]isoquinoline-1,3-dione) is the parent of a new series of anthracene-containing antitumor agents. Its structure is based on amonafide but lacks a primary amine and has an anthracene chromophore rather than a naphthalene chromophore. Using a rat liver cytosol incubation and HPLC/MS detection, we have identified four metabolites re...

The main goal of the study was the analysis of the parameters of wastewater generated during the ex situ underground coal gasification (UCG) experiments on lignite from Belchatow, and hard coal from Ziemowit and Bobrek coal mines, simulated in the ex situ reactor. The UCG wastewater may pose a potential threat to the groundwater since it contains high concentrations of inorganic (i.e., ammonia ...

The ground-(S0) and excited-(S) and Ti) state spectra o f seven derivatives o f 9-acetoxy10(4'-acetoxy)phenylanthracene were determined in the region 50000 15000 cm -1 (200 — 660 nm). Comparison o f these spectra to the unsubstituted molecule (anthracene) indicates the presence o f bathochromic shift and the steric effect. The substituents cause changes o f positions of the energy levels (bigge...

The carcinogenicity of 35 compounds was evaluated in young female Sprague-Dawley rats 9 months after the oral feeding of 10 doses at the maximally tolerated level. The following compounds were definitely active in causing breast cancer: 2-anthramine, 2,7-fluorenediamine, benzidine, Af-6-(3,4-benzocoumarinyl) ace tumide, [<*-(2-methylhydrazino)toIuoyl]urea, and 7,12-dimethylbenz[a]anthracene, th...
