Breakthrough in Organic Semiconductor Synthesis Paves the Way for Advanced Electronic Devices

January 15, 2024

The research team led by Professor Young S. Park from the Department of Chemistry at UNIST has achieved significant breakthroughs in the field of organic semiconductors. They successfully synthesized and characterized a new molecule called "BNBN anthracene", opening up new possibilities for the development of advanced electronic devices.
BNBN anthracene derivatives contain serrated edge BOBN units converted into continuous BNBN units. Compared with traditional anthracene derivatives composed only of carbon, BNBN anthracene exhibits significant changes in CC bond lengths and has a larger highest occupied molecular orbital-lowest unoccupied molecular orbital energy gap. When used as a blue host in organic light-emitting diodes (OLEDs), BOBN anthracene exhibits an extremely low driving voltage of 3.1V, as well as higher efficiency in terms of current utilization, energy efficiency, and luminescence.
The research was published online in December and was supported by the medium-sized research enterprise SFC and promoted by the National Research Foundation (NRF) of the Ministry of Science and ICT under a project of the Ministry of Trade, Industry and Energy.
