[C(NH2)3]2[C2H5(C2O4)]Cl: rational design of a metal-free UV birefringent crystal through the synergistic assembly of three distinct motifs
{{output}}
Developing metal-free birefringent crystals is of great significance in laser technology. Herein, a metal-free birefringent crystal, [C(NH2)3]2[C2H5(C2O4)]Cl, was rationally obtained via a hydrogen-bond-directed assembly of three distinct motifs. It exhibits a... ...
