Innocent BN bond substitution in anthracene derivatives.
Extended azaborine heterocycles are promising biomedical and electronic materials. Herein we report the synthesis of a novel family of azaborine anthracene derivatives and their structural, electrochemical and spectroscopic characterization. We observe that the properties of these materials are remarkably similar to the parent hydrocarbons, suggesting the innocence of the CC to BN bond substitu...
متن کاملCarcinogenicity of derivatives of 7,12-dimethylbenz(a)anthracene.
Eleven derivatives of 7,12-dimethylbenz(a)anthracene were tested for carcinogenicity in Sprague-Dawley female rats by the s.c. injection of 1.0 or 0.1 mg of compound dissolved in 0.1 ml of sesame oil on alternate days for 20 doses. Eight derivatives [7-hydroxymethyl-12-methyl-, 7-formyl-l 2-methyl-, 7-methoxymethyl-l 2-methyl-, 7-acetoxymethyl-l 2-methyl-, 7-benzoyloxymethyl-l 2-methyl-. 7-iodo...
متن کاملAnalogizing the Electronic Coupling Efficiency of Anthracene and its Derivatives
In this paper, we elucidated the observational changes in conductance of different anthracene derivatives namely anthracene, anthraquinone, anthracenediamine and anthracencedithiol through two-terminal molecular junctions at room temperature. The main purpose of this work was to show varying impacts of interference phenomena in anthracene molecule stringed to two identical electrodes by differe...
متن کاملElectronic structures and spectra of conducting anthracene derivatives
Theoretical studies on anthracene and a series of its derivatives were performed using the AM1 method and DFT. Based on B3LYP/6-31G(d) optimized geometries, the electronic, IR and NMR spectra of anthracene oligomers were calculated using the Indo/Cis, AM1 and B3LYP/6-31G(d) methods, respectively. The energy gaps of the oligomers decreased and the main absorptions in the electronic spectra of th...
متن کاملSilylethynylated Anthracene Derivatives for use in Organic Light-Emitting Diodes
We have prepared a series of trialkylsilylethynylated anthracenes (a–d) to investigate the effects of solid-state interactions and acene substitution on the electroluminescence spectra of OLED devices. We designed these materials to have differing amounts of -face interactions and various film morphologies. We were particularly interested in intermolecular interactions between aromatic faces, w...
