The present invention relates to a conjugated aromatic compound represented by the Formula (1) in claim
1
(in the formula, Ar
1
represents a hydrogen atom or an aryl group optionally having a substituent; Ar
2
and Ar
3
each represent a hydrogen atom or an aryl group optionally having a substituent but at least one of Ar
2
and Ar
3
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 (vd)) and high secondary dispersion characteristics (θg,F) (anomalous dispersion characteristics).
本发明涉及一种由权利要求书中的式(1)表示的共轭芳香化合物(在该式中,Ar1代表氢原子或可选择具有取代基的芳基;Ar2和Ar3各自代表氢原子或可选择具有取代基的芳基,但至少Ar2和Ar3中的一个代表可选择具有取代基的芳基;A代表芳香烃基),并涉及包含该共轭芳香化合物的光学材料。该共轭芳香化合物和光学材料具有高色差校正功能、高折射率色散特性(阿贝数(vd))和高二次色散特性(θg,F)(异常色散特性)的特点。
