Isoindigotin BiologicalActivity

Description	Isoindigo is the acceptor of donor-acceptor (D-A) conjugated polymer, as well as an Indigo series dye. Isoindigo equips two lactam rings and strong electron-withdrawing character. Isoindigo can be used for dyeing and pigment preparation. Isoindigo shows high mobility and good ambient stability in FETs[1].
