To obtain a new organic compound used for an electric charge- transporting material for a photosensitive material of an electrophotography, the electron-transporting material and a light-generating material of an organic electric field light-generating element, or various organic semiconductor elements, and to provide methods for producing them.

A new aromatic methylidene compound is expressed by formula (1) (R11 is a non-substituted or substituted alkyl or alkoxy, a halogen, cyano or nitro; n11 is 0-4; and R21, R31 are each H, a non-substituted or substituted alkyl, a non-substituted or substituted cycloalkyl, a non-substituted or substituted aromatic group, a non-substituted or substituted aromatic heterocyclic ring group, or R21 and R31 together form a condensed ring of the non-substituted or substituted aromatic ring or a condensed ring of the non-substituted or substituted aromatic heterocyclic ring), and a methylstyryl compound for producing the same is obtained and the methods for producing them are provided.
