USTC's Research on Four-Dimensional Optical Storage Is Highlighted by the Royal Society of Chemistry of the U.K

  • update:2010-06-07

         The Photonics and Polymer Laboratory of the School of Chemistry and Materials Science, collaborating with the Photonic Information Technology Laboratory of the Department of Precision Machinery and Instrumentation of the School of Engineering Science of USTC, succeeded in realizing polarized many bands and high-density optical information storage by utilizing the light responsiveness of azobenzene. In their study, supramolecular double azobenzene with a good optical property, stability, solubility and processing capacity was prepared to serve as a storage medium, and four-dimensional information storage, with an information density 20 times that of a normal DVD, was realized by means of the laser direct-writing technique. The research results were published in the Journal of Material Chemistry and highlighted across the Royal Society of Chemistry in a May 26 special report entitled "Polymers give DVD upgrade" (http://www.rsc.org/Publishing/ChemTech/Volume/2010/07/polymers_dvd.asp). Meanwhile, RSC's electronic journal "Chemistry World" also carried the news (http://www.rsc.org/ChemistryWorld).
