1,5-DIAMINOANTHRAQUINONE Usage And Synthesis

Uses

1,5-Diaminoanthraquinone (DAAQ) may be used in the preparation of vertical nanowire arrays. It may be used in the synthesis of poly(1,5-diaminoanthraquinone) (PDAA) particles, via chemically oxidative polymerization of DAAQ.

General Description

1,5-Diaminoanthraquinone (DAAQ) is an organic dye compound. Rapid preparation of 1,5-diaminoanthraquinone nanofibers (DAAQNFs) decorated with small platinum nanoparticles (PtNPs) has been reported. The absorption and fluorescence spectra of DAAQ has been investigated in various organic solvents. Preparation of vertical organic nanowire arrays of DAAQ on solid substrates by a facile physical vapor transport method has been reported.

Synthesis

1,5-Diaminoanthraquinone is prepared by SO3H exchange from anthraquinone-1,5-disulfonic acid, by replacing NO2 in 1,5-dinitroanthraquinone, , or by reducing 1,5-dinitroanthraquinone with sodium sulfide or by catalytic hydrogenation .

Purification Methods

Recrystallise it from aniline (m 313-314o) EtOH or acetic acid [Flom & Barbara J Phys Chem 89 4481 1985]. [Beilstein 14 H 303, 14 I 467, 14 II 116, 14 III 466, 14 IV 479.]
