Organic Semiconductor Electroluminescent Materials

Abstract

This chapter reviews the important progress made on small molecule electroluminescent materials used in organic light-emitting diode (OLED). In many cases we describe not only the material structures but also the properties associated with these materials, such as energy level, absorption and photoluminescence (PL) peaks, PL quantum yield, exciton life time, and so on. The performances of related devices are covered as well if they are available.

3-(4-Formylphenyl)-triazole functionalized coumarins as violet-blue luminophores and n-type semiconductors: synthesis, photophysical, electrochemical and thermal properties

“…In this regard, SO fluorophores have been used for bioimaging applications, 2,3 organic optoelectronics 4 and organic light-emitting diodes (OLEDs). 5,6 The violet-blue luminescence is very important in OLEDs, as one of the three primary colors for white light generation. 7 In addition, promising applications in high-density information storage 8 and biological photo-inactivation, 9 among others, have also been reported.…”
