@article{6818, abstract = {Indigoidine is a blue natural pigment, which can be efficiently synthetized in E. coli. 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.}, author = {Yumusak, Cigdem and Prochazkova, Anna Jancik and Apaydin, Dogukan H and Seelajaroen, Hathaichanok and Sariciftci, Niyazi Serdar and Weiter, Martin and Krajcovic, Jozef and Qin, Yong and Zhang, Wei and Zhan, Jixun and Kovalenko, Alexander}, issn = {0143-7208}, journal = {Dyes and Pigments}, publisher = {Elsevier}, title = {{Indigoidine - Biosynthesized organic semiconductor}}, doi = {10.1016/j.dyepig.2019.107768}, volume = {171}, year = {2019}, }
