Synthesis and Characterization of Azobenzene-Based Gold Nanoparticles for Photo-Switching Properties

A series of new azobenzene based thiolated liquid crystals modified with gold nanoparticles were synthesized and characterized using a different mode of delegated tools e.g. FTIR, NMR and FESEM–EDX measurements for the structural properties of synthesized compounds. Polarized optical microscopy stud...
