In this study, we report three new dyes adopting an amide group as the electron-accepting and anchoring unit. Blue-black dye INPBA and INPDT consisting of indole donor, thiophene bridge and thioxo-pyrimidine-dione/pyrimidine-trione acceptors, exhibited maximum absorption wavelength (λmax) at 615 nm and 585 nm, respectively, and extended the cut-off wavelength in near-infrared zone. INPOD exhibited
