Book Description
Organic light-emitting diode technology is evolving rapidly with commercial applications in recent years. OLED materials and design are moving into an advanced stage with optimising techniques becoming more important. This work presents the use of porphyrin materials for organic electronics, specifically for organic light-emitting diodes using phosphorescent emission. The porphyrins show interesting photophysical properties which allow for an exploitation of the normally forbidden triplet energy states to achieve a significant enhancement in the device efficiency. This research presents a simple host–guest system where this concept is demonstrated. Various porphyrin structures are synthesised and tuned for OLED performance; from this, we can learn how chemical structure relates to the exciton dynamics and their resulting light emission. It is hoped that this work outlines a possible route to phosphorescent OLED technologies.

Category : Technology & Engineering
Languages : en
Pages : 572
Book Description
Solution-Processed Organic Light-Emitting Devices provides a comprehensive reference on the principles and advances in materials design, device structures, and processing technologies of organic light-emitting diodes (OLEDs). Most importantly, the book analyses the dynamics of thin-film growth from solutions such as solvent orthogonalization, coffee-ring effects, and interfacial adhesion. Exciton generation and utilization, host–guest energy transfer, and interfacial interaction in the solution-processed films are considered with the material and device design to maximize the electroluminescent performance of OLEDs.The book reviews the materials, devices, and technologies dedicated to solution-processed thin-film devices, which are not only applicable to OLEDs but may be adapted to other emerging semiconducting devices due to the similarity in methods (for instance, quantum-dot LEDs and solar cells, and perovskite-based LEDs/photovoltaics/detectors).This book is suitable for researchers in academia and industry working in the materials science and engineering, chemistry, and physics disciplines. - Discusses the most relevant and emerging solution-processable materials for OLED applications - Reviews device engineering to address defects, charge transport, and exciton generation in fabricated solution-processable thin films - Provides the methods to grow multilayered thin films from solutions with organic semiconductors, with particular attention to new technologies to overcome interfacial mixing effects

Electrochemistry of N4 Macrocyclic Metal Complexes
Author: Jose H. Zagal
Publisher: Springer
ISBN: 3319313320
Category : Science
Languages : en
Pages : 442
Book Description
This new edition describes the state of the art regarding metal complexes of N4-ligands, such as porphyrins and phthalocyanines. Volume 2 focuses on the electro assisted use of N4 complexes as biomimetic models for studying several biological redox processes. It focuses on molecular oxygen transport and catalytic activation to mimic monooxygenase enzymes of the cytochrome P450 in particular. It also examines N4 complexes’ use as catalysts for the oxidative degradation of various types of pollutants (organo-halides, for example) and residual wastes. The remarkable activity of these complexes towards a large number of significantly relevant biological compounds makes them excellent candidates as electrode modifiers for electrochemical sensing. This volume also discusses applications of N4 Macrocyclic Metal Complexes to photoelectrochemistry and photocatalysis, and concludes with an exciting section on Electrosynthesis of N4.

Phthalocyanines and Some Current Applications
Author: Yusuf Yilmaz
Publisher: BoD – Books on Demand
ISBN: 9535132555
Category : Science
Languages : en
Pages : 255
Book Description
Since their initial accidental synthesis and characterization in Scotland in the late 1920s, there has been a strong research focus on the use of phthalocyanines (Pcs) as dyes and pigments. In recent years, active research fields have included their use in electrophotography, photovoltaic and solar cells, molecular electronics, Langmuir-Blodgett films, photosensitizers, electrochromic display devices, gas sensors, liquid crystals, low-dimensional conductors, and optical disks. Phthalocyanines possess interesting biological, electronic, optical, catalytic, and structural properties. The main disadvantage is their insolubility in common solvents due to strong intermolecular - interactions. The solubility of phthalocyanines can be increased by various methods such as the formation of anionic and cationic species and both axial and peripheral substitution. Substitution at the nonperipheral and peripheral positions of the benzo moieties usually enhances their solubility in organic solvents. The most important advantage of phthalocyanines compared to porphyrins is that their Q bands lie at longer wavelengths and are considerably more intense. In this book, you will find synthesis and some applications of various phthalocyanine derivatives.
