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.
