A series of polymers with both high refractive index and high Abbe number have been successfully synthesized through the photoclick thiol-ene reaction between the monomers derived from biobased magnolol (or honokiol) and commercial mercaptans and thiophenols. The polymer films not only exhibit a high refractive index and a high Abbe number but also display a transmittance of up to 90% in a range of wavelengths from 550 to 2000 nm and nearly 0% in the UV region. Moreover, these polymers also display low haze values in the visible-light region as well as exhibit good thermostability. These data indicate that they have potential applications for the fabrication of optical lenses and anti-UV coatings. In particular, this series of polymers are readily used for industrialization due to its excellent optical properties but low expense, simplicity, and efficiency of synthesis.
一系列具有高折射率和高阿贝数的聚合物已经通过单体衍生自生物基厚朴酚（或和厚朴酚）与商业巯基化合物和噻吩之间的光点击硫醇-烯反应成功合成。聚合物薄膜不仅表现出高折射率和高阿贝数，而且在 550 至 2000nm 的波长范围内具有高达 90%的透过率，在紫外区域几乎为 0%。此外，这些聚合物在可见光区域还表现出低雾度值，并且具有良好的热稳定性。这些数据表明它们在制造光学透镜和抗 UV 涂层方面具有潜在的应用。特别是，由于其出色的光学性能、低廉的成本、合成的简单性和高效性，这一系列聚合物很容易实现工业化。
