摘要

9,9-双（4-羟基苯基）芴（BPF）是一种结构高度对称的双酚，具有低双折射和高折射率的优异光学特性，但其聚酯的玻璃化转变温度（Tg）较高（Tg>300°C），难以进行热加工，限制了其应用。另一方面，4,4′-硫代双（2-甲基苯酚）（T2MP）具有柔性硫醚基团，它的引入不仅能带来高折射率，还能适当降低聚合物的 Tg。因此，我们结合两者的优点，制备出了具有高折射率和稳定性的芳香族聚酯。这项研究提供了一种在不损失折射率的情况下适当降低 Tg 的途径。

Design, synthesis and characterization of high refractive index aromatic polyesters containing fluorene and thioether groups

9,9-bis(4-hydroxyphenyl)fluorene (BPF) is a highly structurally symmetric bisphenol with excellent optical properties of low birefringence and high refractive index, however, the glass transition temperature ( Tg) of its polyester is high ( Tg>300°C), which makes it difficult to be thermally processed and limits its application. On the other hand, 4,4′-Thiobis (2-methylphenol) (T2MP) has a flexible thioether group, its introduction not only brings high refractive index, but also can appropriately reduce the Tg of the polymer. Therefore, by combining the advantages of both of them, we prepared aromatic polyesters with high refractive index and stabilization. This study provides a route that can appropriately reduce Tg without loss of refractive index.

期刊介绍： Health Services Management Research (HSMR) is an authoritative international peer-reviewed journal which publishes theoretically and empirically rigorous research on questions of enduring interest to health-care organizations and systems throughout the world. Examining the real issues confronting health services management, it provides an independent view and cutting edge evidence-based research to guide policy-making and management decision-making. HSMR aims to be a forum serving an international community of academics and researchers on the one hand and healthcare managers, executives, policymakers and clinicians and all health professionals on the other. HSMR wants to make a substantial contribution to both research and managerial practice, with particular emphasis placed on publishing studies which offer actionable findings and on promoting knowledge mobilisation toward theoretical advances. All papers are expected to be of interest and relevance to an international audience. HSMR aims at enhance communication between academics and practitioners concerned with developing, implementing, and analysing health management issues, reforms and innovations primarily in European health systems and in all countries with developed health systems. Papers can report research undertaken in a single country, but they need to locate and explain their findings in an international context, and in international literature.
