摘要：

Second-order optical nonlinearity exists in a noncentrosymmetric crystal. We investigated a new molecular concept for noncentrosymmetric crystal structure. The LAMBDA-shaped molecules have been found to easily form noncentrosymmetric crystals by stacking along one direction. The configuration of LAMBDA-shaped molecules is close to an optimum condition for crystal phase-matched nonlinearity. We demonstrate that methanediamine derivatives forming LAMBDA-shaped conformation are promising as efficient chi(2) materials.
