Modulation des propriétés d'isomères de diSpirofluorène-indénofluorène pour des applications en diodes électroluminescentes organiques bleues

Abstract : This work is focused on the synthesis and study of 3π-2spiro molecules, DiSpiroFluorene-IndenoFluorene (DSF-IF), having different structures. These compounds are aimed to be used as blue light emitting layer in OLED. The first chapter describes the working principles of OLEDs and their different structures. It focuses then on different approaches of molecular engineering towards ambipolar molecules that can be used in single layer devices. The second chapter is devoted to the study of two different families of DSF-IF isomers that are obtained through one and the same synthetic intermediate. The different structure of the indenofluorene backbone, (1,2-b) or (2,1-a), leads to different properties, mainly because of intramolecular π-π interactions. The third chapter is related to the development of functionalized DSF-IF with electron donor and/or acceptor groups. The impact of the electron donor or acceptor groups substituted on the DSF-IF are discussed, especially the intramolecular charge transfer phenomena. In the last part, some of these new molecules have been tested as emitting layers in OLEDs
