本文介绍了一种非常简短、高产且汇聚式的合成方法，其底物适用范围广，能够合成具有四重取代双键的多种多样的半硫代靛红。利用这种方法，可以轻松引入碳以及氮、氧或硫基取代基，从而提供大量新颖的结构基序。可见光照射研究表明，这些发色团在波长高达625纳米时具有良好的光开关性能。
A very short, high yielding, and convergent synthesis with broad substrate scope, enabling access to a very diverse range of hemithioindigos with 4-fold substituted double-bonds, is presented. With this method, carbon as well as nitrogen, oxygen, or sulfur based substituents can easily be introduced, delivering a wide array of novel structural motifs. Irradiation studies with visible light demonstrate proficient photoswitching properties of these chromophores at wavelengths up to 625 nm.
