通过将不同长度的正烷基链从甲基调整为辛基,合成了一系列咔唑酰胺衍生物(CAC- N,N= 1–8)。它们的光物理行为高度依赖于它们的烷基链的奇偶校验。也就是说,具有偶数烷基链的化合物表现出有效的机械发光(ML)和强室温磷光(RTP),然而,在奇数对应物中没有观察到 ML 和较差的 RTP。为了让结果更清晰,实验室合成了重要的起始原料咔唑,从中重新合成了上述八种咔唑酰胺衍生物进行比较。尽管 RTP 特性受到商业咔唑中杂质的干扰,但 ML 特性保持不变。单晶分析表明,通过氢键相互作用,在偶数和奇数 CAC 晶体中分别形成了交联网络和孤立的二聚体,这应该解释奇偶交替 ML 现象。此外,通过在 CAC-8 的 ML 基质中掺杂各种有机染料,实现了从蓝色到红色的多色 ML。据我们所知,这项工作是首次观察到 ML 属性中的奇偶效应。

A series of carbazole amide derivatives were synthesized by adjusting the n-alkyl chain with different lengths from methyl to octyl (CAC-N, N = 1–8). Their photophysical behaviors were highly dependent on the parity of their alkyl chain. That is, compounds with even-numbered alkyl chains exhibited efficient mechanoluminescence (ML) and strong room temperature phosphorescence (RTP), however, no ML and
