  烷基取代基对结晶噻吨酮衍生物分子堆积和发光性能的影响

  摘要：

  噻吨酮（TX）及其衍生物作为重要的三重态敏化剂和光引发剂，引起了光化学研究的极大兴趣；然而，它们的发光特性受到的关注较少，这限制了对其结构和特性之间相关性的理解。这里，在TX的2位和4位上引入一系列烷基链（甲基（Me）、乙基（Et）、丙基（ n -Pr）和异丙基（ i -Pr）），主要研究堆积结构与所得晶体的发光特性之间的相关性。发现烷基取代基对分散状态的TX-2-烷基和TX-4-烷基化合物的光物理性质的影响可以忽略不计；然而，单晶X射线衍射分析和光物理测量表明， TX-2-烷基和TX-4-烷基晶体呈现出独特的堆积图案，导致不同的发光特性。 TX-2-Me 、 TX-4-Me 、 TX-4- n -Pr和TX-4- i -Pr晶体显示出二聚 π-π 堆积基序； TX-2- n -Pr和TX-4-Et晶体表现出长程π-π单体堆积图案， TX-2-Et和TX-2- i -Pr晶体表现出人字形堆积图案。
