近年来，聚碘酸盐优异的非线性光学性质已被详细讨论和报道，但其作为双折射材料的潜在应用的探索仍处于初步阶段。我们报道了一种新型有机-无机杂化胍(C(NH 2 ) 3 + , GU)基聚碘酸盐，即C(NH 2 ) 3 Rb(I 3 O 8 )(IO 3 )(I 2 O 6 H 2 )，它是通过水热法获得的。它表现出一种有趣的三维（3D）网络结构，由2D ∞ [C(NH 2 ) 3 Rb(I 3 O 8 )(IO 3 )(I 2 O 6 H 2 )层通过氢键相互作用组成。 C(NH 2 ) 3 Rb(I 3 O 8 )(IO 3 )(I 2 O 6 H 2 )具有0.286@1064 nm的大计算双折射，带隙为3.54 eV，表明其作为紫外双折射材料的潜在应用。理论计算证实，令人印象深刻的光学性能归因于C(NH 2 ) 3 + 阳离子和聚碘酸盐基团之间的协同效应。 • 我们首先将平面单元C(NH 2 ) 3 + 与聚碘酸酯基团结合，通过简便的方法获得了前所未有的具有大双折射的有机-无机杂化聚碘酸酯。 • 我们证明，通过用胍基C(NH 2 ) 3 + 取代Rb + 原子，双折射显着增加。 • 我们首先通过聚碘酸盐和胍基团的协同作用获得了具有大双折射的化合物。
Recently, the excellent nonlinear optical properties of polyiodates have been discussed and reported in detail, but the exploration of their potential application as birefringent materials is still in the preliminary stage. Here we reported a novel organic–inorganic hybrid guanidinium (C(NH 2 ) 3 + , GU)-based polyiodate, namely, C(NH 2 ) 3 Rb(I 3 O 8 )(IO 3 )(I 2 O 6 H 2 ), which was obtained via hydrothermal method. It exhibits an interesting three-dimensional (3D) network structure composed of 2D ∞ [C(NH 2 ) 3 Rb(I 3 O 8 )(IO 3 )(I 2 O 6 H 2 ) layer via hydrogen bonding interactions. C(NH 2 ) 3 Rb(I 3 O 8 )(IO 3 )(I 2 O 6 H 2 ) possesses a large calculated birefringence of 0.286@1064 nm with a band gap of 3.54 eV, indicating its potential application as a UV birefringence material. Theoretical calculations confirm that the impressive optical properties are attributed to the synergistic effect between C(NH 2 ) 3 + cation and polyiodate groups. • We first combine planar unit C(NH 2 ) 3 + with polyiodate groups to obtain an unprecedented organic–inorganic hybrid polyiodate with large birefringence via facile method. • We demonstrate that substantial rise in birefringence received via the substitution of Rb + atom by guanidine group C(NH 2 ) 3 + . • We first obtain a compound with large birefringence via synergistic effect of polyiodates and guanidine groups.
