We herein reported our strategy to assemble planar π-conjugated [B(OH)3] and [C2O4]2-/[HC2O4]-/[C4O4]2- functional groups to explore short-wavelength birefringent crystals. Three compounds, K2C2O4·B(OH)3, Cs4(HC2O4)2(C2O4)·[B(OH)3]2 and K(C4O4)0.5·B(OH)3, which all exhibit a layered structure favorable for generating large optical anisotropy, were synthesized and characterized. The strategy of assembling π-conjugated [B(OH)3] and C-O functional modules shows the potential to explore promising UV birefringent materials.
