In addition to its antioxidant and antimicrobial activities indigoidine due to its stability and deep blue color can find an application as an industrial, environmentally friendly dye. Moreover, similarly to its counterpart regular indigo dye, due to its molecular structure, indigoidine is an organic semiconductor. Fully conjugated aromatic moiety and intermolecular hydrogen bonding of indigoidine result in an unusually narrow bandgap for such a small molecule. This, in its turn, result is tight molecular packing in the solid state and opens a path for a wide range of application in organic and bio-electronics, such as electrochemical and field effect transistors, organic solar cells, light and bio-sensors etc. Elsevier2019 eng 0143-7208 00048487070009910.1016/j.dyepig.2019.107768 171 Yumusak C, Prochazkova AJ, Apaydin DH, Seelajaroen H, Sariciftci NS, Weiter M, Krajcovic J, Qin Y, Zhang W, Zhan J, Kovalenko A. 2019.
