Second-order nonlinear optical organic crystals based on a “click” compound

Abstract

Click chemistry has been employed for the fabrication of second-order nonlinear optical organic crystals BPTA with efficient second harmonic generation responses.

Oxidation-Induced Dissolution Recrystallization Structural Transformation Strategy Enhanced Nonlinear Optical Effect of Hybrid Chiral Tin Bromide Single Crystals

“…SHG signals related to the polarization angle were collected at intervals of 10° in order to study the impact of polarization on the SHG response. The polarization diagram shows that the profile of the curve can be accurately fitted to the cos 4θ function (Figure b), which is consistent with the earlier results. − The polarization dependence of R -2-mpip­[SnBr 3 ]Br exhibits a typical two-lobe shape and the greatest SHG signals at about 80 and 260°. For the p -analyzer, the computed polarization ratio, ρ = ( I max – I min )/( I max + I min ), was found to be 67.8%.…”
