Abstract Long chain derivatives of halogen free carbazoledioxazine which is a typical organic pigment with a linear type structure (5,15‐dialkyl‐5,15‐dihydrodiindolo[3,2‐ b :3′,2′‐ m ]triphenodioxazines) and an angular type structure (5,15‐dialkyl‐7,17‐dialkoxy‐5,15‐dihydrodiindolo[2,3‐ c :2′,3′‐ n ]triphenodioxazines) were newly synthesized. Their structures were confirmed by 1 H‐nmr, ms and elemental analysis. The thermal, spectroscopical and electrochemical properties were investigated by means of DSC, uv‐vis and cyclic voltammetry.
