The triphenylamine azo compounds were successfully characterized by matrix-assisted laser desorption-ionization time of flight mass spectrometry(MALDI-TOF MS).
This paper reviews the literature on the potential of detoxification, transformation and mineralization of nitroaromatic and azo compounds under anaerobic conditions.
The tautomeric equilibrium between the azo type and the hydrazone type of these compounds in different solvents and different acidity has also been studied.
The photoemissions are showed after dichroitic azo dyes doping with liquid crystal,such as widening angle of view, improving light in display and so on.
Dichroitic azo dyes play an important role in the color liquid crystal displays because of their characteristic structure and the ability of being chemical modified.
In order to overcome the disadvantage of low rubfastness of conventional pigment dyeing , a new type covering pigment with ultramicro azo dye as core and acrylate adhesive as shell was presented.
