Available in PDF, EPUB and Kindle. Book excerpt: Organic light emitting diodes (OLEDs) enable the energy-efficient generation of light, and thus find application for displays or lighting. In particular, luminescent copper(I) complexes present a promising, resource- and cost-efficient class of emitting materials for OLEDs and have attracted enormous interest due to their high emission efficiencies and color tunability by ligand variation. The assessment of thermally activated delayed fluorescence (TADF) to copper(I) compounds has accelerated the development and investigation of several complex classes. Herein, novel emitting materials based on mononuclear neutral copper(I) complexes of the type [(NN)Cu(PP)] have been developed and a deeper understanding of the structureproperty relationships was achieved by comprehensive spectroscopical studies. The investigation of a large variety of complexes by absorption and emission spectroscopy, supported by theoretical calculations and electrochemical measurements, enabled a thorough understanding of the steric and electronic effects of the ligands on the complexes' emission. Furthermore, the mechanism of thermally activated delayed fluorescence could be illustrated by means of time-resolved emission spectroscopy, and the intersystem crossing of a representative TADF complex determined in the solid state for the first time, which is essential for the design of efficient TADF materials.

Available in PDF, EPUB and Kindle. Book excerpt: The field of organic electronics has seen a steady growth over the last 15 years. At the same time, our scientific understanding of how to achieve optimum device performance has grown, and this book gives an overview of our present-day knowledge of the physics behind organic semiconductor devices. Based on the very successful first edition, the editors have invited top scientists from the US, Japan, and Europe to include the developments from recent years, covering such fundamental issues as: - growth and characterization of thin films of organic semiconductors, - charge transport and photophysical properties of the materials as well as their electronic structure at interfaces, and - analysis and modeling of devices like organic light-emitting diodes or organic lasers. The result is an overview of the field for both readers with basic knowledge and for an application-oriented audience. It thus bridges the gap between textbook knowledge largely based on crystalline molecular solids and those books focusing more on device applications.

This book was released on 2020 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic light emitting diodes (OLEDs) typically exhibit low quantum efficiencies (~ 19%) due to quantum mechanical limitations and spin statistics. In traditional OLEDs, the emitting excitons are either singlet (25%) or triplet (75%) spin states. Because decay from triplet states is spin forbidden, the internal quantum efficiency of fluorescent devices is limited to a theoretical maximum of 25%. To circumvent this problem, modern OLEDs rely on triplet, phosphorescent emitters, that require the incorporation of often expensive heavy atoms to facilitate intersystem crossing between the singlet and triplet excited states, thus increasing triplet emission. In contrast to the widely explored triplet emitters, this thesis will describe our recent efforts to prepare cationic and neutral doublet emitters derived from carbenes and triarylmethyl- or triarylboryl-centered radicals, respectively. In principle, doublet emitters have theoretical quantum efficiencies of up to 100%, making them ideal candidates for next-generation light-emitting devices. Carbenes will be incorporated into the triarylmethyl- and triaryl boryl- compounds in order to change the emission color as well as stabilize the radical.
