Structural and spectral characterization of novel non-centrosymmetric 2,4-dintrobenzene derivative

Abstract

A novel organic compound 9-(2,4-dinitrophenyloxy)-3,3,8-trimethyl-1,5- dihydro-[1,3]dioxepino[5,6-c]pyridine (DNPAP) has been synthesized and a nonlinear optical (NLO) crystal has been grown by slow evaporation method. Compound was subjected to different characterization analyses in order to find out its suitability for optoelectronic applications. Single crystal and powder X-ray diffraction analyses show that DNPAP crystallizes in the orthorhombic space group Pca21. The range of optical absorption was ascertained by recording UV-Vis spectrum. The second harmonic generation (SHG) test has shown that DNPAP possesses 6.4-times higher NLO efficiency compared to KDP. © 2013 Elsevier B.V. All rights reserved.
