Résumé

The possibility of using push-pull systems based on furazanopyrazine in organic light-emitting diodes (OLEDs) and photovoltaic film devices was shown for the first time. The emission of all the obtained light-emitting diodes had a yellow-green color, and a maximum brightness of 45600 cd m−2 was achieved at a maximum current efficiency of 2.9 cd A−1. It was determined that the mobility of charge carriers measured in different current modes for these push-pull systems ranged from 10−4 to 4 · 10−6 cm2 V−1 s−1, considerably exceeding the values of the well-known compound Spiro-MeOTAD, widely used in high-efficiency photovoltaic devices.
