Light Induced Properties of Chalcones Correlated with Molecular Structure and Photophysical Properties for Permanent Optical Storage Device

Abstract

The photoisomerization effect on new chalcone derivative is reported. The synthesized chalcone was characterized by different spectral analysis such as1H-NMR,13C-NMR, FTIR, LCMS and UV/Vis. It revealed the photoisomerization effect in solution, theE-Zisomerization occurred around 60sec, whereasZ-Eisomerism occurred at 0min. This chalcone derivative is more useful in fabrication of permanent optical storage devices.

Synthesis and Light Induced Characteristics of Siloxane Substituted Azobenzene: An Application for Optical Storage Device

“…Mainly, performance of the optical storage device is based on the nature of chemical structure [4] and functional group [2] of the organic compounds which are used. Also the properties of illuminated light [5] are another important factor which gives impact in the device capabilities. However, the chromophoric functional groups are responsible for the isomerization [6] and molecular reorientation [7].…”

Photo‐induced characteristics of azobenzene based gold nanoparticles

“…Introduction: Currently, sensors, optical storage and molecular switches have a great interest in optically active nanoparticles [1,2]. The E-Z (trans-cis) isomerisation initiates using the irradiation of light energy to the system [3][4][5][6][7]. The π-π* transition takes place in the N = N moiety via UV light (365 nm) illumination.…”

“…This could happen spontaneously without any external aid and the process is called back relaxation (BR). Rapid BR is occurring in the excited molecular system via illumination of ∼450 nm visible light [4][5][6][7]. Nevertheless, BR is very important phenomenon because of its applicability in information storage devices [7][8][9][10].…”

“…Nevertheless, BR is very important phenomenon because of its applicability in information storage devices [7][8][9][10]. Presently, photo-reactive nanoparticles were employed in many research areas namely, photo-switchable surface wettability, molecular switches, optical storage device and molecular recognition applications [1,2,[5][6][7][8][9][10][11]. Hybrid nanocomposites and nano-matrices; which are obtained from organic and inorganic nanoparticles can be extensively useful in optical nano-devices [8][9][10].…”

“…Hybrid nanocomposites and nano-matrices; which are obtained from organic and inorganic nanoparticles can be extensively useful in optical nano-devices [8][9][10]. Among all the organic light sensitive compounds, azobenzene derivatives have promising photo-switching effect and isomerisation properties [4][5][6][7]. Along with azobenzene compounds, other light sensitive organic compounds such as imines and chalcones are also used for the photo-induced studies [8,10].…”
