Switching between second-harmonic generation (SHG) and two-photon-pumped (TPP)
lasing is scientifically important but hard to realize. Herein, a host–guest metal–organic …

Considering nearly infinite design possibilities, organic second harmonic generation (SHG)
molecules are believed to have long-term promise. However, because of the tendency to …

Chalcone structures obtained by structural tailoring are an important class of molecular
organic nonlinear optics (NLO) crystals that can be used for multiple purposes. In this work …

Organic π-conjugated materials have demonstrated superior nonlinear optical (NLO)
performance and serve as ideal candidates for photonic devices. However, the design of …
