Organic semiconductors are an important class of optoelectronic material that are widely studied because of the scope for tuning their properties by tuning their chemical structure, and simple fabrication to make flexible films and devices. Although most effort has focused on developing displays and lighting from these materials, their distinctive properties also make them of interest for visible light communications (VLCs). This article explains how their properties make them suitable for VLC and reviews the main uses that have been explored. On the transmitter side, record white VLC communication has been achieved by using organic semiconductors as colour converters, while direct modulation of organic light-emitting diodes is also possible and could be of interest for display-to-display communication. On the receiver side, organic solar cells can be used to harvest power and data simultaneously, and fluorescent antennas enable fast and sensitive receivers with large field of view. This article is part of the theme issue 'Optical wireless communication'.
有机半导体是一类重要的光电子材料，由于可以通过调整其化学结构来调节其性能，并且易于制造以形成柔性薄膜和器件，因此受到广泛研究。尽管大多数研究致力于利用这些材料开发显示器和照明设备，但它们独特的性能也使其在可见光通信（VLC）领域备受关注。本文解释了它们的特性如何使其适用于VLC，并综述了已探索的主要用途。在发射端，通过使用有机半导体作为颜色转换器，实现了创纪录的白色VLC通信，同时有机发光二极管的直接调制也是可行的，这对于显示器间通信可能具有重要意义。在接收端，有机太阳能电池可用于同时收集能量和数据，而荧光天线则可实现具有大视场的快速且灵敏的接收器。本文是主题为“光无线通信”的系列文章的一部分。
