Four Noncentrosymmetric Molybdophosphates Discovered by Chemical Substitution Strategy
Abstract
Herein, four molybdophosphates, AxB4-xMo5P2O22 (A = Na, K, B = Rb, Cs), were synthesized by cation substitution. Compared with the parent compound A4Mo5P2O22 (A = Rb, Cs), the different cations result in the different polarity of the structural-functional primitive, ultimately influencing the nonlinear optical properties of AxB4-xMo5P2O22 (x = 1-4).
