Non-linear optical properties of DMIT derivatives

Abstract

A number of new DMIT derivatives have been synthesized and their structures have been determined. Among them only chiral BNPT-DTO has significant powder SHG efficiency which varies strongly with the crystal growth solvent and the crystalline temperature; this corresponds to its variability in molecular configuration. DMIT derivatives are also characterized by good crystal habits, good physicochemical stabilities and potentially strong S ⋯ S molecular interactions.
