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.

This document focuses on the DC micro-grid photovoltaic energy storage device, the design of energy storage systems are optical storage hybrid power system which composes the photovoltaic array, battery pack, management systems, photovoltaic inverter, load and power grid. According to the characteristics of the battery and the development of the switching device control technology, the charging and discharging control strategy of battery is studied. In this paper, three-phase inverter is based on the space vector control mode that is called SVPWM, after introducing the basic principle and synthesis method of SVPWM, the on-grid and off-grid system working mode control strategy is studied. Finally the control theory develops the inverter used in the optical storage complementary power generation system, and the article builds test platform to test system, verifying the validity of the control strategy.

Azobenzene Derivatives

The light induced behaviour of siloxane substituted azobenzene compounds in the presence of alkylene spacers is reported for the first time. Firstly, these photosensitive compounds were synthesized and elucidated the molecular structure by spectral analysis such as NMR, FTIR, and UV/Vis. Photoisomerization effect was evaluated in solution and also in nematic phase. The photosaturation occurred exactly at 29 seconds, whereas thermal back relaxation was observed ranging from 19.8 to 23.8 hours. Long duration of the thermal back relaxation is due to the presence of sterically hindered siloxane group substituted to the azobenzene molecules. Decrease in the duration of cis-trans isomerization was found when the number of alkylene spacers was increased. These siloxane based azobenzene derivatives are useful for the fabrication of optical storage device and molecular switches.
