Access to the elusive UV solar‐blind region based on direct second‐harmonic generation (SHG) enabled by a non‐traditional π‐conjugated cation‐based phosphate crystal is reported by Chi Zhang and co‐workers in their Communication on page 14806. The rare coexistence of UV solar‐blind‐region phase‐matchable optical nonlinearity and anisotropy, including wide UV transparency, large SHG response, and sufficient birefringence, can be attributed to the introduction of π‐conjugated cations and their favorable collaboration with phosphate anions.
