Special Issue Information

Dear Colleagues,

Organic light-emitting diodes (OLEDs) are disrupting the display and lighting markets, thanks to their notable characteristics, such as being planar, soft, transparent, fully dimmable, flexible, spectrum tailorable, natural light-style, human-friendly, energy saving, etc. Increasing scientific and technological efforts have been made, not only to stimulate commercialization, but also provide better display and illumination products to the world. Still, there are more blanks to fill with a more competitive OLED technology from lighting perspectives. Hence, we are hoping to publish a Special Issue to gather significant contributions from OLED researchers and experts. This Special Issue aims to offer a platform for latest design strategy of organic molecules, synthesis processes, fabrication routes of OLED devices, and approaches for high efficiency. Manuscripts may be, but are not limited to, the following topics: Efficient OLED materials, efficient OLED devices, the status of white light or monochromes in PM-OLES, AM-OLED, and OLEDs for signage, tandem OLEDs, PIN OLEDs, blue OLEDs, transparent OLEDs, transparent/flexible/wearable OLEDs, printable OLEDs, approaches for long lifetime OELDs, etc.

A series of symmetric sulfone-linked organic fluorescent compounds (1ac) was synthesized and characterized. V-shaped 1ac were designed as aggregate of intramolecular charge transfer (ICT) and aggregation-induced emission enhancement (AIEE) processes. The 1ac emitted intense blue violet lights in normal solvents. A large red shift of the emission wavelength and dramatic decrease of emission efficiency occurred with increasing solvent polarity. The 1ac will function well as electron transport and blue light-emitting materials through theoretical calculations. Full article

Tentative title: Effect of Host Substituents on the Color Purity of Green PHOLED using Platinum Complex Emitter
Tentative abstract: Highly efficient, operationally stable and pure-color organic light-emitting diodes (OLEDs) are of great significance for practical wide-color-gamut displays. In recent years, emitters achieving high color purity have been obtained by employing a planar and rigid molecular structure. We have demonstrated that an efficient pure green phosphorescent OLED (PHOLED) by employing both a platinum complex and a top-emitting structure. Toward the development of pure green PHOLEDs with high operational stability, it is essential to clarify the effect of host materials on the emission spectrum of the platinum complex. This is because the emission spectrum of the platinum complex in a TADF material exhibits a considerably broad emission spectrum, although TADF materials have been reported to be suitable hosts for efficient and stable PHOLEDs. In this study, we investigated the origin of this spectral change by evaluating the photoluminescence of a platinum complex in several hosts with different substituents. From these results, we discuss the design strategy of host materials suitable for maintaining the spectrum shape of platinum complex.
