Outside Back Cover: A Two‐Dimensional Organic Salt With a Deep‐Ultraviolet Cutoff Edge and Strong Second‐Harmonic Generation
In the Communication e7937871, Chao Wu, Chi Zhang, and co-workers report an ultraviolet organic guanidinium salt crystal featuring a honeycomb layered structure. Incorporating aliphatic trifluoroborate anions into a π-conjugated guanidinium system affords a two-dimensional structure that combines strong second-harmonic generations, a deep-ultraviolet cutoff edge, and a calculated shortest phase-matching cutoff wavelength. This work provides a new paradigm for the designed synthesis of high-performance ultraviolet nonlinear optical materials.
