The present invention relates to binaphthyl compounds of the formula (I), which are suitable as monomers for preparing polycarbonate resins having beneficial optical properties and which can be used for producing optical lenses: Formula (I) where X is C2-C4-alkandiyl or C1-C4-alkandiyl-C(O)—, where C(O) is bound to the oxygen atom of the hydroxyl group and where C2-C4-alkandiyl or C1-C4-alkandiyl, respectively, are unsubstituted or carry a phenyl ring; R and R′ are identical or different and selected from mono or polycyclic aryl having from 6 to 36 carbon atoms and mono- or polycyclic hetaryl having a total of 5 to 36 atoms, which are ring members, where 1, 2, 3 or 4 of these atoms are selected from nitrogen, sulfur and oxygen, while the remainder of these atoms are carbon atoms, where mono- or polycyclic aryl and mono- or polycyclic hetaryl are unsubstituted or carry 1 or 2 radicals Ra, which are selected from the group consisting of CN, CH3, OCH3, O-phenyl, O-naphthyl, S-phenyl, S-naphthyl, CI or F; and, if X is C1-C4-alkandiyl-C(O)—, the esters thereof, in particular the C1-C4-alkylesters thereof.
本发明涉及式(I)的联萘化合物,该化合物适合用作制备具有良好光学特性的聚碳酸酯树脂的单体,并可用于生产光学镜片:式(I) 其中 X 是 C2-C4-alkandiyl 或 C1-C4-alkandiyl-C(O)- ,其中 C(O) 与羟基的氧原子结合,C2-C4-烷基或 C1-C4-alkandiyl 分别是未取代的或带有一个苯基环;R 和 R′相同或不同,选自具有 6 至 36 个碳原子的单环或多环芳基和具有 5 至 36 个原子的单环或多环庚基,它们是环状成员,其中 1、2、3 或 4 个原子选自氮、硫和氧、单环或多环芳基和单环或多环庚二基未经取代或带有 1 或 2 个基 Ra,这些基可从 CN、CH3、OCH3、O-苯基、O-萘基、S-苯基、S-萘基、CI 或 F 组成的组中选出;如果 X 是 C1-C4-烷二基-C(O)-,则是其酯,特别是其 C1-C4 烷基酯。
