摘要

Abstract > New symmetric and unsymmetric B,N,B‐doped benzo[4]helicenes 3 – 6?a/b have been achieved in good yields, using a three‐step process, starting from N(tolyl) <sub>3</sub> 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?a / 2?b via intramolecular borylation and sequential B?Mes bond cleavage in the presence of BBr <sub>3</sub> . Subsequent reaction of 2?a / 2?b with Ar‐Li provided a highly effective toolbox for the preparation of symmetrically/unsymmetrically functionalized B,N,B‐helicenes. Their high photoluminescence quantum yields along with the small Δ E <sub>ST</sub> suggest their potential as thermally activated delayed fluorescence (TADF) emitters for organic light‐emitting diodes (OLEDs). </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden"
