SDS of cas: 591-18-4 And the article was included in Angewandte Chemie, International Edition in 2020. The article conveys some information:

The meta junction is proposed to realize efficient thermally activated delayed fluorescence (TADF) in donor-acceptor (D-A) conjugated polymers. Based on triphenylamine as D and dicyanobenzene as A, as a proof of concept, a series of D-A conjugated polymers has been developed by changing their connection sites. When the junction between D and A is tuned from para to meta, the singlet-triplet energy splitting (ΔEST) is found to be significantly decreased from 0.44 to 0.10 eV because of the increasing hole-electron separation Unlike the para-linked analog with no TADF, consequently, the meta-linked polymer shows a strong delayed fluorescence. Its corresponding solution-processed organic light-emitting diodes (OLEDs) achieve a promising external quantum efficiency (EQE) of 15.4% (51.9 cd A-1, 50.9 lm W-1) and CIE coordinates of (0.34, 0.57). The results highlight the bright future of D-A conjugated polymers used for TADF OLEDs.

Quality Control of 1-Bromo-3-iodobenzeneIn 2021 ,《Hypsochromic Shift of Multiple-Resonance-Induced Thermally Activated Delayed Fluorescence by Oxygen Atom Incorporation》 was published in Angewandte Chemie, International Edition. The article was written by Tanaka, Hiroyuki; Oda, Susumu; Ricci, Gaetano; Gotoh, Hajime; Tabata, Keita; Kawasumi, Ryosuke; Beljonne, David; Olivier, Yoann; Hatakeyama, Takuji. The article contains the following contents:

Herein, we reported an ultrapure blue multiple-resonance-induced thermally activated delayed fluorescence (MR-TADF) material (ν-DABNA-O-Me) with a high photoluminescence quantum yield and a large rate constant for reverse intersystem crossing. Because of restricted π-conjugation of the HOMO rather than the LUMO induced by oxygen atom incorporation, ν-DABNA-O-Me shows a hypsochromic shift compared to the parent MR-TADF material (ν-DABNA). An organic light-emitting diode based on this material exhibits an emission at 465 nm, with a small full-width at half-maximum of 23 nm and Commission Internationale de l’Eclairage coordinates of (0.13, 0.10), and a high maximum external quantum efficiency of 29.5%. Moreover, ν-DABNA-O-Me facilitates a drastically improved efficiency roll-off and a device lifetime compared to ν-DABNA, which demonstrates significant potential of the oxygen atom incorporation strategy.

Organic Light Emitting Diodes (OLEDs), as lighting materials, have great application potential. Compared with fluorescent OLEDs, phosphorescent OLED devices can produce higher luminous efficiency, which is favored by many researchers. Among them, the key material of OLED is an important factor affecting the performance of this kind of device. In this study, the carbazole group and the 1,2,4-Triazole group with high hole transport properties were used as research materials, and four bipolar main materials of Triazole-carbazole group were prepared by mixed reaction under high temperature and catalyst conditions. One of the materials (4PTBB) was selected as carbazole derivative, and the D. Functional Theory (DFT) was introduced to study the carrier transport properties of the derivatives in quantum chem. During the experiment, the physicochem. properties of the four Triazole-carbazole bipolar host materials were analyzed. These new materials exhibited good thermal stability (Td: 418-448 degree), high glass transition temperature (Tg: 127-149 °C) and high triplet energy level (ET: 2.38 eV-2.78 eV); and the electron mobility of 4PTBB (5.77 x 10-2 cm2 · V-1 · s-1) was two orders of magnitude higher than hole mobility (5.89 x 10-4 cm2 · V-1 · s-1). The above results indicated that the Triazole-carbazole bipolar host material has good thermal stability and good electron transport performance, and it can be used for phosphorescent OLED devices to exhibit better performance.
