The combination of Sn or Sb with π, non-π-conjugated units has produced birefringent crystals with birefringence ranging from 0.005 to 0.468@1064 nm. It is proven that introducing Sn or Sb into crystals is a feasible strategy to enlarge the birefringence, which not only promotes the miniaturization of fabricated devices, but also effectively modulates polarized light. Herein, recently discovered Sn , Sb -based birefringent crystals with birefringence investigated are summarized, including their crystal structure and optical properties, especially birefringence. This review also presents the influence of Sn , Sb with stereochemically active lone pair on the optical anisotropy. We hope that this work provides a clear perspective on the crystal chemistry of Sn , Sb -based optical functional crystals and promotes the development of new birefringent crystals with large optical anisotropy.
将 Sn 或 Sb 与非共轭π单元结合，产生了双折射晶体，其双折射范围为 0.005 至 0.468@1064nm。已经证明，将 Sn 或 Sb 引入晶体是增大双折射的可行策略，这不仅促进了制造器件的小型化，而且有效地调制了偏振光。本文总结了最近发现的具有双折射的 Sn 、 Sb 基双折射晶体，包括它们的晶体结构和光学性质，特别是双折射。本综述还介绍了具有立体活性孤对电子的 Sn 、 Sb 对光学各向异性的影响。我们希望这项工作为 Sn 、 Sb 基光学功能晶体的晶体化学提供一个清晰的视角，并促进具有大光学各向异性的新型双折射晶体的发展。
