报道了一系列具有各种侧链取代基的二氢茚并[1,2- b ]芴(IF)衍生物的合成,已经通过单晶X射线分析对它们的分子堆积和热稳定性进行了研究。通过DSC测量观察到这些形态。结果表明,带有较长线性脂族侧链的对称取代的IF倾向于在不耐热共平面层中结晶,其中脂族和二氢茚并[1,2- b]芴核链段在空间上是分开的。与此相反,芳基侧链与二氢茚并芴核的连接导致界面形态的稳定,这可以通过不存在热相变来观察到。除此之外,还合成了具有可变长度的成对线性脂肪族侧链以及芳基取代基的不对称取代的衍生物,即所谓的“混合茚并芴”(MIF)。这些衍生物倾向于表现出热稳定的形态,并具有形成二氢茚并芴结构的边对面接触的趋势。

which properly designed molecular components are positioned in space by reliable interactions. In principle, this approach can be used to control the arrangement of adjacent systems of π-conjugation, thereby creating molecular materials with valuable optoelectronic properties. To explore this possibility, we have synthesized compounds in which 2,4-diamino-1,3,5-triazinyl groups are attached to derivatives
