Effect of a twin-emitter design strategy on a previously reported thermally activated delayed fluorescence organic light-emitting diode
Beilstein J. Org. Chem. 2021, 17, 2894–2905, doi:10.3762/bjoc.17.197
- orientation with anisotropy values in the range 0.06 to 0.12, depending on the host materials. However, in going from vacuum deposition, which was possible for the low-molecular weight emitter ICzTRZ, toward solution processing required for the much bigger DICzTRZ, one can expect significant changes of the
Synthesis of novel multifunctional carbazole-based molecules and their thermal, electrochemical and optical properties
Beilstein J. Org. Chem. 2020, 16, 1066–1074, doi:10.3762/bjoc.16.93
- synthesised solar cells (DSSCs) and sensors [1][2]. In OLEDs, carbazole derivatives are frequently used as host materials [3][4][5]. In this respect the most frequently used host materials are 1,3-bis(N-carbazolyl)benzene (mCP) [6] and polyvinylcarbazole (PVK) [7]. Carbazole derivatives, either just by
Aryl-substituted acridanes as hosts for TADF-based OLEDs
Beilstein J. Org. Chem. 2020, 16, 989–1000, doi:10.3762/bjoc.16.88
- stability of light-emitting layers and consequently for elongation of device lifetimes [11]. Proper energy levels and bipolar charge-transporting properties of host materials may endow good charge-injection properties and charge balance in the guest–host light-emitting layers of TADF OLEDs [12][13][14
- ]. Therefore, the synthesis of host materials with the combination of all required properties especially of those intended for blue TADF OLEDs is a great challenge [11][15]. Up to now, most of the compounds used as hosts in TADF-based devices demonstrate a deep HOMO energy level and shallow LUMO energy level
Recent advances in materials for organic light emitting diodes
Beilstein J. Org. Chem. 2018, 14, 1944–1945, doi:10.3762/bjoc.14.168
- molecular design approach for orange-emitting TADF molecules employing a fluorenone acceptor [5]. In the full research paper by Feng-Ming Xie et al., they disclose two bipolar, high-energy phenothiazine-5,5-dioxide-based host materials conceived to be used for deep blue OLED devices [6]. The articles in
- this thematic issue provide a window into the design principles used towards the development of next-generation emitter and host materials for OLEDs. I hope these articles will provide inspiration for further research in this exciting area. Eli Zysman-Colman St Andrews, June 2018 Eli Zysman-Colman
Two novel blue phosphorescent host materials containing phenothiazine-5,5-dioxide structure derivatives
Beilstein J. Org. Chem. 2018, 14, 869–874, doi:10.3762/bjoc.14.73
- , Jiangsu 215009, P.R. China Department of Materials Science and Engineering, Monash University, Clayton, Victoria 3800, Australia 10.3762/bjoc.14.73 Abstract Two novel D–A bipolar blue phosphorescent host materials based on phenothiazine-5,5-dioxide: 3-(9H-carbazol-9-yl)-10-ethyl-10H-phenothiazine-5,5
- as suitable HOMO and LUMO energy levels. This preferable performance suggests that CEPDO and CBPDO are alternative bipolar host materials for the PhOLEDs. Keywords: host materials; phenothiazine; phosphorescence; synthesis; Introduction Since 1987, the Tang group [1] firstly reported double organic
- selection of proper materials for each layer is very important for achieving highly efficient PhOLEDs. In particular, the design of host materials plays a critical role in the determination of the devices performance. Therefore, it is beneficial to develop new blue phosphorescent host materials with high
