The first synthesis of a tetracene BN isostere is reported. Comparison with its direct, all-carbon analogue reveals that the BN tetracene isostere exhibits a lower-lying HOMO and a slightly larger optical HOMO–LUMO gap. While all-carbon tetracenes are prone to photodecomposition, the BN tetracene scaffold is less light sensitive, owing in part to its much higher photoluminescence quantum yield. In the context of this larger BN tetracene family, we introduce simple guiding principles for predicting frontier orbital energies as a function of the position of the BN unit within the tetracene scaffold.

BN Tetracene:扩大并苯中BN / CC等位基因的研究范围

据报道并四苯并氮杂环丁烷的第一个合成。与它的直接全碳类似物的比较表明,BN并四苯醚等排物的HOMO-LUMO间隙较低,而HOMO-LUMO光学间隙稍大。虽然全碳四碳烯容易发生光分解,但BN并四碳支架对光的敏感性较低,部分原因是其光致发光的量子产率高得多。在这个更大的BN并四苯族中,我们引入了简单的指导原则,用于预测边界线能量与并四苯骨架中BN单元位置的关系。
