One-Pot Synthesis of 9-Aminomethylanthracene
Glowacka, Paulina C.,Stephenson, G. Richard
, p. 1733 - 1737 (2016)
A novel method for the preparation of 9-aminomethylanthracene has been developed by the use of ammonium salts in the reductive amination of the 9-formyl anthracene derivative, a reaction which has been examined with a variety of reducing agents, ammonium ion sources, and solvents. The optimized reaction conditions allowed the isolation of the fluorophore in good yields.
Cu2 fluorescent sensor based on mesoporous silica nanosphere

Monodisperse mesoporous silica nanosphere (MSN) modified with anthracene derivative, 2-(3-(triethoxysilyl) propylamino)-N-(9-anthryl methyl) acetamide (SGAAn) has been fabricated as a fluorescent sensor (SGAAn-MSN) for the detection of metal ions, which shows an exclusive selectivity to Cu2. Compared with SGAAn, SGAAn-MSN presents a higher sensitivity to Cu2. The loading amount of SGAAn in MSN has a great influence on the detection sensitivity of SGAAn-MSN, which varies with the local concentration and accessibility of SGAAn in the pore channel of MSN. Interference studies indicate that the addition of other metal ions such as Ag+, Cd2 and Pb2 has a negligible effect on the selectivity of SGAAn-MSN to Cu2. The possible mechanism for the sensing behavior of SGAAn-MSN to Cu2 is proposed based on the relation between fluorescence quench degree and Cu2 concentration.

, p. 7943 - 7946 (2009)
(Chemical Equation Presented) A fluorescent chemodosimeter containing a guanidiniocarbonylpyrrole and a 9-(aminomethyl)anthracene moiety has been synthesized. The sensor exhibits ratiometric fluorescence changes for SO 32- over other anions in 90% water/DMSO. The interesting ratiometric fluorescent changes for SO32- are attributed to the fluorescence resonance energy transfer (FRET) and the SO3 2- complex induced photochemical reaction. 2009 American Chemical Society.

Reductive Amination by Photoredox Catalysis and Polarity-Matched Hydrogen Atom Transfer

The excitation of a RuII photosensitizer in the presence of ascorbic acid leads to the reduction of iminium ions to electron-rich α-aminoalkyl radical intermediates, which are rapidly converted into reductive amination products by thiol-mediated hydrogen atom transfer (HAT). As a result, the reductive amination of carbonyl compounds with amines by photoredox catalysis proceeds in good to excellent yields and with broad substrate scope and good functional group tolerance. The three key features of this work are 1) the rapid interception of electron-rich α-aminoalkyl radical intermediates by polarity-matched HAT in a photoredox reaction, 2) the method of reductive amination by photoredox catalysis itself, and 3) the application of this new method for temporally and spatially controlled reactions on a solid support, as demonstrated by the attachment of a fluorescent dye on an activated cellulose support by photoredox-catalyzed reductive amination.
