Synthesis and Characterization of New Mesomorphic Azo Compounds and Study their Photoluminesecence Properties

الملخص

The preparation of a new Azo compounds of highly conjugated dimeric and polymeric liquid crystal to achieve the crystalline characteristics Which have structures assigned based on elemental analysis, IR 1HNMR and CHNS-O while mesogenic properties have been set for DSC and hot-stage polarizing optical microscopy. The compounds show enantiotropicnematic phase being displayed.
The compounds show photoluminescence properties in the organic solution at room temperature, with the fluorescence band centered around 400 nm.
