New sym. and unsym. B,N,B-doped benzo[4]helicenes 3–6闁?strong>a/b have been achieved in good yields, using a three-step process, starting from N(tolyl)3 in a highly divergent manner (7 examples). A borinic acid functionalized 1,4-B,N-anthracene 1 was found to display unprecedented reactivity, acting as a convenient and highly effective precursor for selective formation of bromo-substituted B,N,B-benzo[4]helicenes 2闁?strong>a/2闁?strong>b via intramol. borylation and sequential B-Mes bond cleavage in the presence of BBr3. Subsequent reaction of 2闁?strong>a/2闁?strong>b with Ar-Li provided a highly effective toolbox for the preparation of sym./unsym. functionalized B,N,B-helicenes.

Isomeric thermally activated delayed fluorescence emitters based on a quinolino[3,2,1-de]acridine-5,9-dione multiple resonance core and carbazole substituent was written by Liu, Jing-Feng;Zou, Sheng-Nan;Chen, Xing;Yang, Sheng-Yi;Yu, You-Jun;Fung, Man-Keung;Jiang, Zuo-Quan;Liao, Liang-Sheng.

The color purity of the pixels is an essential indicator in organic light-emitting diode (OLED) com. displays. Since the two important parameters of high color purity and efficiency can be achieved simultaneously, multiple resonance thermally activated delayed fluorescence (MR-TADF) emitters have achieved rapid development. Recently, there has been a lot of research work on connecting various donor (D) moieties to the existing MR core, but few studies on how the linking moiety affects the efficiency of MR-TADF emitters. To figure out the influence of substituents on the MR-TADF system, we developed three isomers QAOCz1, QAOCz2, and QAOCz3, which are constructed with the same moieties of 3,11-diphenylquinolino[3,2,1-de]acridine-5,9-dione and 9-phenyl-9H-carbazole (PhCz) by different site connections. Through reasonable adjustments of the substitution site, the donor-acceptor (D-A) interaction of the isomers gradually weakened and mol. rigidity gradually increased. As a result, their singlet-triplet energy gap (铻朎ST) gradually decreased and their photoluminescence quantum yield (PLQY) gradually rose. QAOCz3 with the weakest D-A interaction successfully achieves a much higher PLQY of 98.9% and a smaller 铻朎ST of 0.16 eV. The QAOCz3 based OLED not only realizes the best maximum external quantum efficiency (EQE) of 21.1% but also has the narrowest full-width at half maximum (FWHM) of 40 nm. This work shows that weakening the D-A interaction between the substituents and the MR core by a spacer group is of great significance for the construction of efficient MR-TADF emitters.
