title: Spectral, thermal and optical properties of adenosinium picrate: a nonlinear optical single crystal.
abstract: A new organic nonlinear optical material adenosinium picrate (C10H14N5O4+, C6 H2 N3 O7-) was synthesized. The single crystal X-ray diffraction revealed the non-centrosymmetric crystal structure, which is an essential criterion for second harmonic generation. The crystalline nature of the grown crystals was confirmed using powder XRD techniques. Molecular structure was confirmed by NMR spectral analysis and functional groups were identified by FT-IR spectral analysis. The optical transmittance window and the lower cutoff wavelength of the AP have been identified by UV-vis-NIR studies. Thermo gravimetric analysis (TGA) and differential thermal analysis (DTA) were used to study its thermal properties. Powder test with Nd:YAG laser radiation shows second harmonic generation.
