Resumo: Recent developments in OLED (Organic Light-Emitting Diode) technology have led to a strong understanding of processes governing electroluminescence. Nowadays, special organic materials are developed to satisfy the need for efficient and stable OLED electroluminescence. Among desired features of OLED emitters one is extremely important: they must harvest as much excited states as possible and efficiently turn them into photons. In typical case 25% of singlet and 75% of triplet states are generated in an OLED device. Only some classes of OLED emitters are able to harvest the triplet states and these are the most desired in current technology.
