Incorporation of a CN group into mCP: a new bipolar host material for highly efficient blue and white electrophosphorescent devices
Ming-Shiang Lin,Shang-Jung Yang,Hong-Wei Chang,Yi Hsiang Huang,Yu-Tang Tsai,Chung-Chih Wu,Shu-Hua Chou,Ejabul Mondal,Ken-Tsung Wong +8 more
TL;DR: In this article, a novel bipolar host material mCPCN has been designed and synthesized by incorporating the electron-accepting CN group into the well-known benchmark host materialmCP, which significantly improves thermal/morphological stabilities and increases the electron affinity.
Journal ArticleDOI
Fluorene‐Based Asymmetric Bipolar Universal Hosts for White Organic Light Emitting Devices
TL;DR: In this paper, two new bipolar host molecules composed of holetransporting carbazole and electron-transporting cyano (CzFCN) or oxadiazole-substituted fluorenes are synthesized and characterized.
Journal ArticleDOI
A dicarbazole–triazine hybrid bipolar host material for highly efficient green phosphorescent OLEDs
Chih-Hao Chang,Ming Cheng Kuo,Wei-Chieh Lin,Yu Ting Chen,Ken-Tsung Wong,Shu-Hua Chou,Ejabul Mondal,Raymond Kwong,Sean Xia,Tetsuya Nakagawa,Chihaya Adachi +10 more
TL;DR: In this article, a bipolar host material 9-(4,6-diphenyl-1,3,5-triazin-2-yl)-9′-phenyl-3,3′-bicarbazole (CzT) comprising a dicarazole donor linking to an electron deficient 1, 3, 5-triazine acceptor was synthesized and characterized, allowing the spatial separation of HOMO and LUMO on the donor and acceptor moieties, respectively, giving sufficient triplet energy (2.67 eV
Journal ArticleDOI
Carbazole-based coplanar molecule (CmInF) as a universal host for multi-color electrophosphorescent devices

TL;DR: In this paper, a carbazole-based coplanar molecule (CmInF) obtained through the intramolecular ring closure of aryl substitutions at the C3 and C6 positions exhibits a high triplet energy (ET = 2.77 eV), morphological stability (Tg = 195 °C) and hole mobility in the range of up to 5 × 10−3 cm2 V−1 s−1.
Journal ArticleDOI
An environmentally benign synthesis of aurones and flavones from 2′-acetoxychalcones using n-tetrabutylammonium tribromide
TL;DR: A wide variety of aurones (3a-f ) can be prepared exclusively from 2′-acetoxychalcones (1a-,f ) in high yields in two steps, by bromination using n-tetrabutylammonium tribromide (TBATB) in the presence of CaCO3 in CH2Cl2-MeOH (5:2) at 0-5°C followed by cyclization of the brominated products 2a-, f on treating with 0.2 M ethanolic KOH solution at 0−5
