Photoactivatable anthracenes

supporting information, p. 3973 - 3981 (2014/05/20)
Fifteen substituted maleimide cycloadducts of anthracene derivatives were synthesized in one or two steps from available precursors in yields ranging from 32 to 63%. They differ in the nature of the group on the maleimide nitrogen atom and of the substituents on the anthracene platform. In all instances, the introduction of a maleimide bridge across positions 9 and 10 of the anthracene skeleton isolates electronically its peripheral phenylene rings and suppresses its characteristic fluorescence. The cycloadducts with a 4-(dimethylamino)phenyl group on the maleimide nitrogen atom undergo retro-cycloaddition upon ultraviolet illumination with quantum yields ranging from 0.001 to 0.01. This structural transformation restores the aromatic character of the central ring of the oligoacene chromophore and activates its emission with fluorescence quantum yields ranging from 0.07 to 0.85. Thus, this particular choice of building blocks for the construction of photoresponsive compounds can translate into viable operating principles for fluorescence activation and, ultimately, lead to the realization of valuable photoactivatable fluorophores for imaging applications.

The framework of altertoxin III, a mycotoxin produced by Alternaria fungi investing food and feed, has been synthesised for the first time. Synthetic schemes including Diels-Alder reactions of anthracene derivatives turned out to be not successful due to
A New Convenient Synthesis of Alkoxyanthracenes from Alkoxy-9,10- anthraquinones

Methoxy-9,10-anthraquinones with mono-, di- and tetraether groups at different positions 1a-h can be directly reduced to the corresponding methoxyanthracenes 3a-h in moderate to good yields by zinc in refluxing acetic acid. Under similar conditions, ethyl 1′-anthracenoxyacetate (3i) with the ester group unaffected and 1,8-oxybis(ethyleneoxyethyleneoxy)anthracene (5) were also conveniently synthesized in 65 and 70% yields, respectively.
Bimolecular formation of radicals by hydrogen transfer. 14: The uncatalyzed transfer hydrogenation of α-methylstyrene by 2,6-disubstituted 9,10-dihydroanthracenes
Keller, Friedrich,Ruechardt, Christoph
, p. 642 - 648 (2011/10/09)
2,6-Dimethoxy- (4a), 2,6-bis(dimethylamino)- (4b), 2,6-dichloro- (4c) and 2,6-dimethoxycarbonyl-9,10-dihydroanthracene (4d) were prepared by conventional methods and used as hydrogen transfer donors to α-methylstyrene (5) between 290-350°C. The mechanism

, (2008/06/13)
An anthracene derivative having at least two groups of the formula: STR1 wherein R1 and R2 are independently hydrogen, alkyl, alkoxy, etc., is particular effective for forming an antireflection coating for preventing multiple reflection of exposing light from a highly reflective substrate, etc.
Deep ultraviolet absorbent and its use in pattern formation
-
, (2008/06/13)
A deep ultraviolet absorbent comprising at least one compound having one or more glycidyl groups in the molecule and at least one anthracene derivative, and a solvent capable of dissolving these compounds is effective for preventing reflection of deep ultraviolet light from a substrate during formation of resist pattern, resulting in forming ultra-fine patterns without causing notching and halation.
