Photoisomerization behavior of photochromic amide-based azobenzene dyes exhibiting H-bonding effect: Synthesis and characterization

Amide linkage was introduced into azo compound at para position and its optical storage properties were investigated. Synthesized compounds showed liquid crystalline behavior when electron withdrawing group was inserted in the chemical structure. UV/Vis study showed that the photoisomerization eff...
