4-methylphenyl Azo Research Articles

Synthesis of (3,4-bis{[2-hydroxy-3-methoxy-5-(4-methylphenyl azo)benzylidene]-amino}phenyl) phenyl methanone as a novel azo Schiff base

Schiff bases are used as substrates in the preparation of a large of bioactive and industrial compounds via ring closure, cycloaddition, replacement reactions, etc [1].[...]

Effect of Lateral Hydroxy/Alkoxy Group on Mesomorphism of Azobenzene Derivatives

Two homologous series are synthesized by fixing a rigid 4-methyl phenyl azo group to resorcinol moiety. In series I one phenolic -OH group is alkylated whereas, in series II both the phenolic -OH groups are alkylated. Monoethers of series I having free lateral hydroxy group due to strong hydrogen bonding, exhibit nematic mesophases whereas, diethers of series II are non-mesogenic.
