A group of scientists from the Novosibirsk Organic Chemistry Institute of the Siberian Branch of the Russian Academy of Science, the Novosibirsk State University and the Groningen University (Netherlands) have developed an organic material suitable for making flexible electronic devices. It has the best properties among all the materials designed for the purpose so far, the press service of the NSU reports in the environment.
"We aim at simplifying the process of producing gadgets. Production of inorganic semiconductors is currently related to complicated technologies, which require high temperatures and vacuum. Organic materials, however, can be applied in cheaper and easier ways, such as for example, printing a semiconductor layer. Unique properties of these materials can promote creation of new devices, such as, for example, a flexible visual display, which can be folded or rolled and put in a pocket", - one of the developers, the employee of free radicals chemistry laboratory of the NSU, Maxim Kazantsev explained.
Similar materials suitable for creating flexible displays are now actively developed worldwide. Such properties as electricity conductivity and the output of photoluminescence (i.e. glow generated by light quanta) are important for them.
Siberian chemists became the first-ever to have grown up uniform crystals with such properties from a solution. Moreover, they have attained a record output of photoluminescence, which makes about 65 percent, whereas its main analogs have only 35 percent.
Mr. Kazantsev pointed out, that some other crystals received by scientists earlier show such parameters as well. However, the Siberian and Dutch chemists have managed to attain these results in an easier and cheaper way.
Results of the studies are published in the prestigious scientific journal RSC Advances. Developers plan to be engaged in preserving and improving the properties of the grown crystals.
Earlier the TASS reported about Tomsk scientists' plans of by 2017 to print the first domestic samples of displays from the "ink" created by the Russian chemists on the basis of organic semiconductors. Researchers plan to get the first samples of printed organic electronics at the end of 2016.
