靛蓝是一种蓝色天然色素，可以在大肠杆菌中高效合成。大肠杆菌。除了具有抗氧化和抗菌活性之外，靛蓝还因其稳定性和深蓝色而可以作为工业环保染料得到应用。此外，与对应的常规靛蓝染料类似，由于其分子结构，靛蓝是一种有机半导体。完全共轭的芳香族部分和靛蓝啶的分子间氢键导致这种小分子的带隙异常窄。这反过来又导致固态分子紧密堆积，并为有机和生物电子领域的广泛应用开辟了道路，例如电化学和场效应晶体管、有机太阳能电池、光和生物传感器等。
Indigoidine is a blue natural pigment, which can be efficiently synthetized inE. 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.
