摘要：

Make your OLED fluorescent: An aromatic molecule based on a spiro-acridine derivative was designed (see picture), and its photoluminescence and electroluminescence were characterized. By combining the donor and acceptor moieties a small energy gap between the lowest singlet and triplet states was achieved. This design leads to an organic light-emitting diode (OLED) that rivals phosphorescent devices regarding exciton generation efficiency. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
