报道了一种合理化的方法来调节顺丁烯二酸的光学性质。本文研究了一系列主链含二茂铁或茂二茂铁结构单元的高分子量聚芳烯的光学性质。通过改变金属、取代基或间隔元件，可将聚异戊二烯的折射率从1.599调谐至1.747。计算了主链重复单元RfcE {其中fc = [（η 5 -C5 H4）2 -Fe]，E = Si，Ge，Sn或P}的摩尔折射率为57.2 ~ 63.6cm3/mol，符合摩尔折射的加和原理.主链重复单元的摩尔折射率的值，R fcE，被用来预测分子定制的聚二茂铁的折射率。聚二茂铁的光学色散，其特征在于阿贝数，被证明是低于具有类似的折射率的有机聚合物。
A rationalized approach to tuning the optical properties of metallocenes is reported. The optical properties of a series of high molecular weight polymetallocenes with main chain ferrocene or ruthenocene units were examined. The refractive indices of polymetallocenes were tuned from 1.599 to 1.747 by modifying the metal, the substituent group, or the spacer element. The molar refraction of the backbone repeating unit, R fcE , {where fc = [(η 5 -C 5 H 4 ) 2 -Fe] and E = Si, Ge, Sn, or P} was calculated to range from 57.2 to 63.6 cm 3 /mol and demonstrated to comply to the additivity principle of molar refraction. The value of the molar refraction of the backbone repeating unit, R fcE , was used to predict the refractive index of molecularly tailored polyferrocenes. The optical dispersion of polyferrocenes, characterized by the Abbe number, was demonstrated to be lower than that of organic polymers with similar refractive indices.
