Abstract

The high efficiency and quadratic nonlinear optical properties of 2D octupolar crystal of 1,3,5-tricyano-2,4,6-tris(p-diethylaminostyryl)benzene (TTB), which is characterized by nonlinear microscopy, was analyzed. The TTB single crystals were obtained by evaporating a saturated solution of TTB in CH₂Cl₂-EtOEt. To confirm optically the octupolar crystalline structure and determine the molecular arrangement inside the submillimeter-sized crystal, a polarized nonlinear microscopy technique was applied along with second harmonic generation (SHG) and two-photon fluorescence (TPF). The results show that optical polarization measurements of both SHG and TPF confirmed the non-centrosynmmetric threefold symmetry of the TTB crystal.
