    • 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).
    • 本发明涉及权利要求1中式(1)表示的共轭芳族化合物(式中,Ar 1表示氢原子或任选具有取代基的芳基; Ar 2和Ar 3分别表示氢原子或芳基 任选具有取代基,但Ar 2和Ar 3中的至少一个表示任选具有取代基的芳基; A表示芳族烃基),并且涉及含有共轭芳族化合物的光学材料。 共轭芳族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(ngr·d))和高二次分散特性(& g,F)(异常色散特性) 。
