Thanks to the tremendous effort over the last 20 years, phosphorescent organic light‐
emitting diodes (PhOLEDs) represent a prevalent technology. In this technology, all the high …

The easily rotatable peripheral aromatic rings around central benzene in hexaarylbenzene
(HAB) derivatives create a very intriguing nonplanar, propeller-shaped geometry. Because …

Hole-transporting materials (HTMs) are integral to the construction of a wide variety of state-
of-the-art semiconductor devices today. Insofar as display and lighting technologies based …

In this work, we designed and synthesized three spirobifluorene (SBF)-based hole-
transporting materials (HTMs) by incorporating the di-4-tolylamino group at different …

The ever-increasing demand for energy that necessitates fabrication of optoelectronic
devices for efficient solar harvesting systems has driven scientists towards the development …

The control of molecular orientation in emissive guest− host systems is a promising concept
for efficiency enhancement in state-of-the-art organic light-emitting diodes (OLEDs). 1− 4 …

Grafting six fluorene units to a benzene ring generates a new highly twisted core of hexakis
(fluoren‐2‐yl) benzene. Based on the new core, six‐arm star‐shaped oligofluorenes from …

Electrochromic supercapacitors have drawn enormous attention due to their ability to
monitor the charge and discharge processes through color changes of electroactive …

Carbazole dendrimers up to 4th generation were synthesized. They showed significantly
high Tg, amorphous and stable electrochemical properties, and great potential as solution …

A new host material based on the 2, 7, 4′-substituted spirobifluorene platform has been
designed and used in single-layer phosphorescent OLED with very high efficiency (EQE …
