Abstract

Abstract : A new hybrid fluorooxoborate was discovered following the strategy of combining two birefringence-active units. The large birefringence and short absorption edge make it a potential short-wavelength ultraviolet birefringent crystal. Abstract : The design and preparation of new birefringent materials with large birefringence, especially those for the short-wavelength spectral region, are still active since they play an important role in creating polarized light. Herein, a new organic–inorganic hybrid fluorooxoborate [C3 N6 H7 ]2 [B3 O3 F4 (OH)] was discovered following the strategy of combining two birefringence-active units to increase the optical anisotropy. The large birefringence (0.440@546 nm) and short absorption edge (240 nm) make [C3 N6 H7 ]2 [B3 O3 F4 (OH)] a potential short-wavelength ultraviolet birefringent crystal. Both the [C3 N6 H7 ] cation and [B3 O3 F4 (OH)] anion in [C3 N6 H7 ]2 [B3 O3 F4 (OH)] are identified as birefringence-active units that induce large optical anisotropy, as evidenced by additional theoretical calculations.
