✦ Synopsis

Abstract

The crystalline substance N,N ‐dimethyl anilinium picrate(DMAP) was synthesized and the single crystals of the title compound were grown by slow evaporation solution growth technique at room temperature. The crystalline nature of the material has been confirmed by powder X‐ray diffraction method. The elemental analysis data confirm the stoichiometry and hence the molecular formula of the synthesized material. The formation of the charge‐transfer complex has been confirmed by UV‐visible spectral data. The infrared and ^1^H NMR spectroscopic data indicate a charge transfer activity associated with a proton transfer from the acceptor to the donor followed by intermolecular hydrogen bonding. Thermal behavior and stability of crystal were studied using thermo gravimetric (TG) and differential thermal analyses (DTA) techniques. The second harmonic generation (SHG) of the material was confirmed using Nd: YAG laser. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
