Herein we describe a modular, convergent synthesis of substituted benzo[a]benzo[6,7]‐indolo[2,3‐h]carbazoles (BBICZs) using a bidirectional gold‐catalyzed cyclization reaction as a key step. A building block strategy enabled the easy variation of substituents at different positions of the core structure and a general analysis of substitution effects on the materials properties of the target compounds. All BBICZs were fully characterized and their optical and electronic properties were studied experimentally as well as by computational methods. Organic thin‐film transistors based on eight selected derivatives were fabricated by vacuum deposition and charge‐carrier mobilities up to 1 cm²/Vs were measured.

金催化遇到材料科学-π-扩展吲哚并咔唑的新方法

本文中，我们描述取代的苯并的一个模块化的，汇集合成[一个]苯并[6,7]吲哚并[2,3- ħ ]咔唑使用双向金催化环化反应中的关键步骤（BBICZs）。构造策略使核心结构不同位置的取代基容易变化，并且对目标化合物的材料性质的取代作用进行了一般分析。对所有BBICZ均进行了充分表征，并通过实验和计算方法研究了它们的光学和电子性能。通过真空沉积制造了基于八种选定衍生物的有机薄膜晶体管，并测量了高达1 cm ² / Vs的载流子迁移率。
