Surface and biocidal activity of some synthesized metallo azobenzene isothiouronium salts

A novel series of azobenzene isothiouronium salts of different alkyl chains (propyl, hexyl and dodecyl) were synthesized by reaction of 4-((4-methylphenyl)azo)phenol with 1,3-dibromopropane, 1,6-dibromohexane and 1,12-dibromododecane, respectively. These

Method for preparing polyimide polymer with azo-pyrimidine structure unit

The invention relates to a method for preparing a diamine monomer with an azo-pyrimidine structure and a method for preparing a polyimide polymer by adopting the diamine monomer with the azo-pyrimidine structure. The preparation method comprises the following steps: carrying out a coupling reaction on 4-substituted aniline and sodium phenate to obtain 4-hydroxy-4'-substituted azobenzene; and carrying out nucleophilic substitution on the 4-hydroxy-4'-substituted azobenzene and dibromoalkane to generate bromo-azobenzene, and reacting the bromo-azobenzene with 4,6-diamido-2-mercaptopyrimidine to obtain the diamine monomer; and carrying out condensation polymerization on the diamine monomer with dianhydride to obtain polyimide. The pyrimidine structure is introduced into the diamine monomer, so that the charge transfer complex effect of aromatic rings of polyimide is reduced, and the glass transition temperature of the polyimide is reduced; and the azo group has photo-induced anisotropy, and an azo unit is introduced into the polyimide by alkyl chains having different lengths, so that the heterogeneous degree of the azo group can be effectively regulated, and the application of the polyimide in alignment films and other optical fields can be improved to a great extent.

Azobenzene-Based Organic Salts with Ionic Liquid and Liquid Crystalline Properties

Two sets of new azobenzene-based bromide salts are synthesized, and their thermal photochromic properties are studied. Both sets are based on the imidazolium cation. The first set (1) features a symmetric biscation where two imidazolium head groups (Im) w

Synthesis and characterization of new diamines containing side substituted azobenzene groups

New aromatic diamines containing two side substituted azobenzene groups have been obtained by chemical modification of 2,2-bis(3-amino-4-hydroxyphenyl)-hexafluoropropane with different p-bromoalkyloxy-p'-methyl-azobenzene compounds in the presence of K2CO3/KI. The bromoalkyloxy-methylazobenzenes have been prepared by the reaction of p-hydroxy-p'-methylazobenzene with different dibromoalkanes. All intermediates and the prepared diamines have been characterized by melting points, infrared spectroscopy and proton nuclear magnetic resonance. The new diamines can be used further as monomers for production of new polyimides or copolyimides for high performance applications.

Solvent-dependent photoresponsive conductivity of azobenzene-appended ionic liquids

A new class of azobenzene-based photoresponsive ionic liquids was prepared and showed reversible modulation of ionic conductivity in specific solvents under alternative UV/visible light irradiation.
