NOVELTY - A halogen containing 1,3-diformyl-2-benzothiophene is new.    USE - A halogen containing 1,3-diformyl-2-benzothiophene for manufacturing halogen containing (di)thiaporphyrin (claimed) used in organic electronic device e.g. organic electroconductivity material, organic semiconductor material, n-type organic field effect transistor (OFET), solar cell material, photoconductivity device, non-linear optics material, photoelectric transducer dopant, photoconductivity carrier production material and material for optical recording and catalyst.    ADVANTAGE - The benzothiophene ring has high planarity and can anticipate high carrier mobility.    DETAILED DESCRIPTION - A halogen containing 1,3-diformyl-2-benzothiophene of formula (4) is new.    X41=halo;    R41=(thio)alkoxyl, linear, branched or cyclic aliphatic hydrocarbon group (optionally halogenated), aromatic hydrocarbon group (optionally halogenated), aliphatic heterocyclic group (optionally halogenated), aromatic heterocyclic group (optionally halogenated);    m+n= less than or equal to 4;    m=1-4; and    n=0-3.
