A new birefringent crystal [C(NH2)3]2S2O8 was obtained by combining the π-conjugated [C(NH2)3] cation and the [S2O8] groups with localized O–O π-bonds. Optical measurements show that the UV cutoff wavelength of [C(NH2)3]2S2O8 is 222 nm, and its birefringence is 0.102 at 546 nm. The calculated results show that its large birefringence is attributed to the synergistic effect of the [C(NH2)3] and [S2O8] units, which is the first case among known birefringent crystals. These results provide new insights into the design of superior birefringent materials.

[C(NH2)3]2S2O8：结合离域和局域 π 共轭单元以实现强光学各向异性
将π-共轭[C(NH 2 ) 3 ]阳离子和[S 2 O 8 ]基团与局域O-O π-结合得到一种新的双折射晶体[C(NH 2 ) 3 ] 2 S 2 O 8 。债券。光学测量表明[C(NH 2 ) 3 ] 2 S 2 O 8的紫外截止波长为222 nm，在546 nm处的双折射为0.102。计算结果表明，其较大的双折射归因于[C(NH 2 ) 3 ]和[S 2 O的协同作用。8 ]单位，这是已知的双折射晶体中的第一种情况。这些结果为设计优质双折射材料提供了新的见解。
