AzaBenzannulated PeryleneDiimides (AzaBPDIs) and their nitrogen, sulphur and selenium bay-functionalized derivatives are introduced herein as a new class of n-type semiconductors. Heteroatoms were inserted in one bay prior to the application of a visible-light-driven cyclisation strategy closing a six-membered ring comprising a nitrogen atom on the opposite bay. The electronic and optical properties

生物在本文中作为一类新的 n 型半导体引入。在应用可见光驱动的环化策略之前,杂原子被插入到一个槽中,在对面的槽上封闭一个包含氮原子的六元环。在溶液和薄膜中研究了这些化合物的电子和光学性质。除氮附加衍
生物外,所有
染料都表现为 n 型半导体,对热退火几乎没有敏感性。该演示为设计更复杂的基于 AzaBPDI 的架构打开了大门。
