5,5′-Diiodoindigo (4) exhibits excellent ambipolar transistor properties with hole/electron mobilities of μh/μe = 0.42/0.85 cm2 V-1 s-1. The halogen substituted indigos show decreasing tilt angles from F to I in the crystals. In addition, the iodine-iodine interaction provides extraordinarily large interchain interaction. However, the X-ray diffraction suggests that the indigo molecules are arranged approximately perpendicular to the substrate in the thin films, probably due to the extra iodine-iodine interaction. The remarkable performance is ascribed to this characteristic supramolecular interaction.
Total Synthesis of the Chlorinated Indigo-N-Glycosides Akashin A, B and C

A total synthesis of the indigo-derived natural products akashin A-C was developed. The key step was the N-glycosylation of soluble N-benzylated-indigos with a suitably protected viosaminyl trichloroacetimidate. This donor was obtained from D-galactose. U

The total synthesis of cladoniamide G, a cytotoxic compound against MCF-7 breast cancer cells (10 μg/mL), was accomplished. Key steps in the sequence include oxidative dimerization of 3-acetoxy-5-chloroindole and a tandem process incorporating three steps
