The efficient synthesis of morphologically different heteroacenes and the rapid determination of their solid-state and electronic properties are still challenging tasks, which slow down progress in the development of new materials. Here, we report a flexible and efficient synthesis of unprecedented heterotetracenes based on a platinum- and gold-catalyzed cyclization–alkynylation domino process using
噻吨并呋喃和呋喃酮是有机材料中最常见的分子单元。有效合成形态上不同的杂苯并快速确定其固态和电子性质仍然是具有挑战性的任务,这减缓了新材料开发的进度。在这里,我们报告了在关键步骤中使用乙炔基苯并碘化钾(EBX)高价碘试剂,基于铂和金催化的环化-炔基化多米诺工艺,灵活高效地合成了前所未有的异戊二烯。合成四碳原子的电荷传输性质的计算机模拟原理证明表明,它们强烈依赖于杂原子在环系统中的位置和性质。预计会有广泛的流动性,
