Deep-blue emitting 9,10-bis(perfluorobenzyl)anthracene

Beilstein Journal of Organic Chemistry
A new deep-blue emitting and highly fluorescent anthracene (ANTH) derivative containing perfluorobenzyl (BnF) groups, 9,10-ANTH(BnF)2, was synthesized in a single step reaction of ANTH or ANTH(Br)2 with BnFI, using either a high-temperature Cu-/Na2S2O3 ...

Enzymatic activity of catechol 1,2-dioxygenase and catechol 2,3-dioxygenase produced by Gordonia polyisoprenivorans

Química Nova, 2012
This study aimed to evaluate the environmental conditions for enzyme activity of catechol 1,2-dioxygenase (C1,2O) and catechol 2,3-dioxygenase (C2,3O) produced by Gordonia polyisoprenivorans in cell-free and immobilized extracts.

Ameliorative effects of piroxicam on anthracene-induced lung toxicity in female Rattus norvegicus

Folia Veterinaria
Anthracene present in cigarette smoke may cause tumors of the lungs and other organs. Hence, the therapeutic potential of piroxicam against anthracene-induced lung damage was investigated.

Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges

Angewandte Chemie International Edition, EarlyView.
Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

Crystal structure of (E)-1(anthracen-9-ylmethylidene)[2-(morpholin-4-yl)ethyl]amine

Acta Crystallographica Section E, 2014
The title compound, C21H22N2O, crystallizes with two independent molecules in the asymmetric unit. In both molecules, the anthracene ring systems are almost planar, with maximum deviations of 0.071 (8) and 0.028 (7) Å, and make dihedral angles of 73.4 (2)

Toward Larger Cyclo-9,10-Anthryleneparaphenylenes. [PDF]

Chemistry
During a macrocyclization with a dihydroanthracene diol as corner unit, larger oligomers than the trimer and tetramer were formed and isolated up to the nonamer. Their three‐dimensional structures were studied by X‐ray diffraction. The most abundant macrocycles were rearomatized to the corresponding CPP derivatives.

A Chiral Saddle‐Shaped Nanographene With Two Heptagon‐Embedded [4]Helicenes

Angewandte Chemie International Edition, EarlyView.
We present a novel synthetic strategy toward a chiral saddle‐shaped nanographene (cSNG) via a two‐step oxidation of a prochiral anthracene precursor. The Scholl‐type oxidation first yields a key intermediate with sp3‐defect heptagons, and subsequent oxidative dehydrogenation affords fully conjugated cSNG.

A Reversible 900 nm Near‐Infrared Photoswitch for Invisibly Writable 2D and 3D Displays

Angewandte Chemie International Edition, EarlyView.
The peri‐benzo[a]fluoranthenethioindigo (PBFT) photoswitch enables direct excitation with near‐infrared light up to 900 nm wavelengths. It delivers a high‐performance property profile including high‐contrast color changes between bright green and deep blue.

Anthracene functionalized terpyridines – synthesis and properties

Beilstein Journal of Organic Chemistry, 2010
The synthesis of several symmetrically 4,4″-functionalized 2,2′:6′,2″-terpyridines is reported. In addition to the biscarboxylic acid 4,4″-tpy(CO2H)2 (3), the anthryl esters 4,4″-tpy(CO2CH2Anth)2 (5a) and 4,4″-tpy(CO2CH2CH2OAnth)2 (5b) were synthesized ...
