PURPOSE: To obtain a new material high in thermal stability, highly dense and free from pinhole, capable of providing e.g. amorphous thin films excellent in charge transportability, thus useful for electronic devices. CONSTITUTION: This amorphous molecular material is expressed by formula I [A is of formula II or formula III (X is a chalcogen atom);≠is a n-valent aromatic group havingπelectron conjugated system; n is >=3], e.g. a compound of formula IV. This material, for example, a compound of formula V, is obtained by heating an acid chloride compound bearing the aromatic groupΦand an imino compound in an appropriate solvent in a nitrogen atmosphere to effect dehydrochlorination. This material is useful for organic photoconductors, organic electroluminescent devices, diodes, transistors, etc.
