S. M. Gan,A. R. Yuvaraj,M. R. Lutfor,Mohd. Yusoff Mashitah,Hegde Gurumurthy,Hegde Gurumurthy +5 more
TL;DR: In this paper, a series of fluorinated azobenzene esters have been synthesized and studied by polarized optical microscopy (POM) and UV-Vis spectrophotometry.
Journal ArticleDOI
Synthesis and liquid crystalline behaviour of substituted (E)-phenyl-4-(phenyldiazenyl) benzoate derivatives and their photo switching ability
Gurumurthy Hegde,Govindaswamy Shanker,Siew Mei Gan,A. R. Yuvaraj,Syed Mahmood,Uttam Kumar Mandal +5 more
TL;DR: Azobenzene derivatives containing phenyl/4-halogen-phenyl 4-{(E)-[4-(pent-4-en-1-yloxy)phenyl]diazenyl}benzoate group with different electronegative substituent (H, F, Cl, Br and I) at other end was synthesized.
Journal ArticleDOI
Aliphatic/aromatic spacers based azo dye dimers: synthesis and application for optical storage devices
TL;DR: The photoisomerization effect of new bent-shaped azo dyes in the presence of aliphatic and aromatic spacers is reported for the first time in this paper, where the synthesized compounds with n-hexane and benzene as central moieties were characterized by different spectral analytical techniques such as 1H-NMR, 13C- NMR, FTIR and UV-Vis.
