were synthesized, and their redox and electronic properties and crystal structures were investigated. Solid-state absorption spectra showed that both derivatives absorb almost all visible light. Furthermore isopropylsulfanyl-substituted derivatives absorb near-infrared light and the absorption edge reaches around 1320 nm. The crystal structures show that both derivatives are stacked in one dimension to
