Amphiphilic anthracene derivatives showed solvent-polarity-dependent fluorescence. Monomer emission and aggregation-induced emission (AIE) were observed in polar and non-polar organic solvents, respectively. AIE became predominant in aqueous solution in the case of hexafluorophosphate as a counter anion.

K-region epoxides of dibenz(a,h)anthracene and benz(a)anthracene were more active in producing malignant transforma tion of hamster embryo cells than the corresponding hydrocarbons, K-regions CMand frans-dihydrodiols and phenols. The cytotoxicity exerted by epoxides, relative to the other derivatives, varied among those tested. The 8,9-epoxide (non-K-region) of benz(a)anthracene was less active...

Novel analogues of N-piperazinyl fluoroquinolones were prepared and evaluated against a panel of Gram-positive and Gram-negative bacteria, to study the effect of introducing bulky anthracene and phenanthrene moieties on the antibacterial effects of norfloxacin, ciprofloxacin and gatifloxacin. Although most of the novel synthesized compounds had lower antibacterial effects, some derivatives show...

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...

Abstract The decarboxylative coupling of diversely substituted benzoic acids with internal alkynes proceeds smoothly in the presence a [RhCl(cod)]2/1,2,3,4-tetraphenyl-1,3-cyclopentadiene catalyst system to selectively produce highly naphthalene derivatives. is applicable constructing anthracene and benzo­[c]thiophene frameworks through reactions naphthoic thiophene-2-carboxylic acids, respecti...

Efficient and stereoselective syntheses are described for the preparation of 2,3,9,10-tetrabromo-1,4-dimethoxy-1,2,3,4-tetrahydroanthracenes 7, 8 and the corresponding 1,4-diol 17 by silver ion-assisted solvolysis of hexabromotetrahydroanthracene 6. Base-promoted aromatization of 7 and 8 afforded synthetically valuable tribromo-1-methoxyanthracenes 10 and 11. The reaction of 17 with sodium meth...

In this study, light-emitting diodes (LEDs) used as secure, low-cost and possessing long emission wavelengths irradiation sources were applied in photopolymerization. Seven novel anthracene derivatives (noted A1-A7) proposed evaluated photosensitive systems. Three of them never synthesized before (A1, A2 A7) the other fields. Due to in-silico design molecular structure by modeling, chalcone-ant...
