In recent years, truxenes and related polyaromatic hydrocarbons (PAHs) have engrossed ample interest of the scientific community because of their ease of synthesis, functionalizations, and use as building blocks for the synthesis of fullerene fragments, liquid crystals, larger polyarenes, and C3-tripod materials. In the present work, we have disclosed an ingenious method for the construction of various indolo-truxene hybrid molecules in good yields (52–90%), by means of the acid-catalyzed cotrimerization, Friedel–Crafts acylation, and Fischer indole synthesis, and fully characterized them through the standard spectroscopic techniques. The photophysical properties of the thus-prepared compounds have also been investigated using steady-state absorption and fluorescence and time-resolved fluorescence spectroscopy techniques. Moreover, the density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations have been studied to correlate them with the measured photophysical properties of the synthesized indolo-truxene derivatives.

C3-对称吲哚基 Truxene:设计、合成和光物理研究
近年来,聚苯乙烯和相关的多环芳烃 (PAH) 因其易于合成、功能化以及用作合成富勒烯片段、液晶、较大的聚芳烃和C 3的结构单元而引起了科学界的广泛关注。 - 三脚架材料。在目前的工作中,我们公开了一种巧妙的方法,通过酸催化共三聚、Friedel-Crafts酰化和Fischer吲哚合成,以良好的产率(52-90%)构建各种吲哚-truxene杂化分子,并通过标准光谱技术充分表征它们。还使用稳态吸收和荧光以及时间分辨荧光光谱技术研究了由此制备的化合物的光物理性质。此外,还研究了密度泛函理论(DFT)和时间相关的DFT(TD-DFT)计算,以将它们与合成的吲哚-truxene衍生物的测量光物理性质相关联。
