摘要：
The present invention relates to a conjugated aromatic compound represented by the Formula (1) in claim 1 (in the formula, Ar1 represents a hydrogen atom or an aryl group optionally having a substituent; Ar2 and Ar3 each represent a hydrogen atom or an aryl group optionally having a substituent but at least one of Ar2 and Ar3 represents an aryl group optionally having a substituent; and A represents an aromatic hydrocarbon group) and relates to an optical material containing the conjugated aromatic compound. The conjugated aromatic compound and the optical material have characteristics of a high chromatic aberration correction function, high refractive-index dispersion characteristics (Abbe number (νd)) and high secondary dispersion characteristics (θg,F) (anomalous dispersion characteristics).
