Two resveratrol-based monomers with thermo-cross-linkable trifluorovinyl-ether groups (−OCF═CF₂) have been designed and synthesized. After treating at a temperature above 140 °C, the monomers were converted into cross-linked networks, which display the average dielectric constants (D_k) of 2.45–2.52 and the average dielectric loss (D_f) of 2.2 × 10^–3 to 2.6 × 10^–3 at a high frequency of 5 GHz. Such data are much better than these of the resveratrol-based epoxy resin (D_k of above 3.5 and D_f of near 2.6 × 10^–2) and the commercial bisphenol A epoxy resins (D_k of above 3.7). In addition, two cured monomers exhibit high thermostability with a 5% weight loss temperature (T_5d) of more than 450 °C. They also display low water uptake of below 0.08% when immersed in boiling water for 3 days. These data indicate that the resveratrol-based monomers in this contribution are suitable as the encapsulation resins for the application in the microelectronic industry.

具有高热稳定性和高频介电性能的白藜芦醇基氟化材料

与热交联性三氟-醚基团（-OCF═CF两个基于白藜芦醇的单体₂）已经被设计和合成。在高于140℃的温度下处理后，单体转化成的交联网络，其显示的平均介电常数（d _ķ的2.45-2.52）和平均介电损耗（d _˚F的2.2×10）^-3至在5 GHz的高频下为2.6×10 ^–3。这样的数据比白藜芦醇基环氧树脂（D _k大于3.5和D _f接近2.6×10 ^-2）和市售双酚A环氧树脂（D _k高于3.7）。此外，两种固化的单体在5％的失重温度（T _5d）超过450°C时表现出高的热稳定性。将它们浸泡在沸水中3天后，其吸水率也低于0.08％。这些数据表明，该贡献中的白藜芦醇基单体适合用作微电子工业中的封装树脂。
