摘　　要：以2,7-二溴-9-芴酮、间苯二酚和苯硼酸的衍生物为原料,经过环化、羟乙基化和Suzuki偶联等3步反应,设计并合成了一系列2,7-芳基呫吨螺芴二醇衍生物,通过红外光谱、核磁光谱(^(1)H NMR,^(13)C NMR)、元素分析等表征了化合物的结构。折光率和紫外可见光谱测试结果表明:与2,7-无取代基的呫吨螺芴二乙醇衍生物相比,目标化合物具有更高的折光率(1.66~1.68)和良好的透光率,有望作为聚碳酸酯光学树脂的二醇单体,应用于光学透镜、光学膜等领域。A series of diol derivatives containing the framework of xanthene spirofluorene were designed and synthesized from derivatives of 2,7-dibromo-9-fluorenone,resorcitol and phenylboric acid through three steps of cyclization,hydroxyethylation and Suzuki coupling.The structure of these compounds were confirmed by IR,^(1)H NMR,^(13)C NMR and elemental analysis.The refractive measurements and UV spectra of diol derivatives indicate that they have higher refractive index of 1.66~1.68 and good transmittance,compared with the corresponding parent diol,and so they have a broader application prospect as diol monomers of polycarbonate optical resins in optical lenses and optical films.
