The unprecedented time‐dependent long‐range supramol‐ecular assembly of electron‐deficient hexaazatrinaphthylene (HATN) core based on peripheral crowding with three out‐of‐plane cyclic ketals is reported. The single‐crystal X‐ray structure of the diethyl derivative provided detailed information as to how four molecules in a repeating unit were packed in order to avoid steric crowding of the out‐of‐plane
据报道,基于外围拥挤并带有三个平面外环状缩酮,缺电子的六氮杂萘(HATN)核具有前所未有的时间依赖性远距离超分子组装。二乙基衍生物的单晶X射线结构提供了有关重复单元中如何堆积四个分子的详细信息,从而避免平面外环状缩酮侧链的空间拥挤,从而提供锁定和固定作用以稳定自组装结构。偏振光学显微镜(POM)和差示扫描量热法(DSC)在冷却过程中没有立即显示出任何相变。令我们惊讶的是,POM图像显示24小时后高达100μm的球晶形核。X射线衍射数据进一步证实了这些软晶体形成了六角形晶体。新材料的远程自组装在紫外可见吸收光谱中显示出轻微的红移,并通过计算方法进一步证实。
