Synthesis, two dimensional NMR analysis, DFT, and nonlinear optical investigations of a new cyclic imide

Abstract

Diels Alder reaction is employed to prepare a new cyclic imide. The structure of synthesized cyclic imide (11aR)-2-(2-nitrophenyl)-2,3,5,6,11,11a-hexahydro-1H-6,11-[1,2] benzen-ebenzo [5,6] cyclohepta [1,2-c]pyridine-1,4(4aH)-dione (A3) is characterized by FTIR, Mass, 1D and 2D NMR spectra. Theoretical calculations are performed using density functional theory (DFT) to investigate the possibility of nonlinear optical (NLO) behavior. The NLO properties of the cyclic imide are studied via the calculation of the nonlinear refraction index (NLRI) using diffraction patterns (DPs) and Z-scan. The all-optical switching (AOS) of the prepared cyclic imide is studied using two laser beams.
