Aliphatic/aromatic Spacers Based Azo Dye Dimers: Synthesis and Application for Optical Storage Devices

The photoisomerization effect of new bent-shaped azo dyes in the presence of aliphatic and aromatic spacers is reported for the first time. The synthesized compounds with n-hexane and benzene as central moieties were characterized by different spectral analytical techniques such as 1 H-NMR, 13C-NMR,...
