KF·[SO2(NH2)2]: the First Deep-Ultraviolet Transparent Sulfonamide Fluoride Nonlinear Optical Crystal with Novel Cairo Pentagonal Structure
{{output}}
The sulfonamide group (SO2(NH2)2) shows great potential for deep-ultraviolet nonlinear optical (NLO) crystals due to its strong hyperpolarizability and anisotropy, but its neutrality and poor protonation limit its application. Here, we propose a new design str... ...
