英文摘要Developing superior deep-ultraviolet (deep-uv) nonlinear optical (nlo) materials is a great challenge because of the contradiction between deep-uv transparency and enhanced second harmonic generation (shg), especially for deep-uv nlo phosphates in which the constituent p-o groups have relatively small microscopic shg coefficients. here we report a new noncentrosymmetric phosphate cs2lipo4 (i), whose crystal structure consists of [lipo4](infinity) layered structural units with a novel honeycomb-like topology. as compared with the benchmark deep-uv nlo material kbe2bo3f2 i is beryllium-free, and it is relatively easy to grow its large single crystals because of its congruent melting. furthermore, it not only is deep-uv transparent but also exhibits an unexpectedly enhanced shg response of 1.8 x kh2po4 that hits a new high in deep-uv nlo phosphates. these results demonstrate that i satisfies the key requirements of being a promising deep-uv nlo candidate. theory calculations and structural analysis reveal that the enhanced shg response can be attributed to the honeycomb-like topological structure, which endows the constituent [po4](3-) monomers of i with an aligned arrangement and as a result a favorable superposition of their microscopic shg coefficients. these findings may provide useful insights into the development of both deep-uv nlo materials and honeycomb-like topological structures.
