Advances in Organic Light-Emitting Diodes (#409)

After the demonstration of the first efficient organic light-emitting diode (OLED) by Tang and Van Slyke nearly 30 years ago, extensive studies both in academia and the chemical and electronics industries have led to significant progress in the development of new organic semiconducting molecular and polymer materials, characterization of the electronic and optical processes in thin films, and understanding of the device physics. OLEDs have now entered the display and solid-state lighting markets and represent already a multi-billion $ industry. Contrary to the perception that such successes might no longer justify substantial fundamental research, in reality much work remains to be done especially in terms of development of stable blue emitters, elucidation of the basic degradation pathways, design of chromophores based on sustainable elements, and assessment of new pathways to electroluminescence. Examples of the latter include the recently proposed approaches exploiting either thermally assisted delayed fluorescence or reverse intersystem crossing of hot triplet charge-transfer excitons, which allow (nearly) 100% internal luminescence quantum efficiency in purely organic materials.

This Pacifichem Symposium will provide a truly international platform to discuss recent advances and exchange new ideas in the field of OLEDs and related topics, including the synthesis of new chromophores and materials, characterization of the photochemistry and photophysics mechanisms, theory and modeling, processing pathways (solution vs. vacuum deposition), and real-world applications in displays and solid-state lighting. A diverse set of invited, and contributed, speakers (gender-wise, country-wise, and background-wise) will give the participants the chance to evaluate in depth the present and future of OLEDs.
