In this study, a fluorescent compound; N, N'-Bis (2-Hydroxy Benzylidene) Benzidine, (C26H20N2O2) prepared and calculated by FT-IR, 1H NMR, UV-Vis and fluorescence procedures. The 1H NMR field examined in Chloroform-d solvent. The Fourier Transform-Infrared FT-IR in hard case detected in the area 4000-600 cm-1. The absorption spectrum of the Bis (2-Hydroxy Benzylidene) Benzidine resolved in tetrahydrofuran registered on the range 250-800nm. The fluorescence spectrum show in the region 520-700nm in different pH at room temperature. Photoluminescent properties of the title compound examined in tetrahydrofuran, Chloroform, acetone, and Toluene. The intensity and Stoke’s move of N, N' Bis (2-Hydroxy Benzylidene) Benzidine in THF solvent found greater than other solvents. The structural value, fundamental vibration modes, Proton Nuclear magnetic resonance isotropic chemical changes, and absorption spectrum of the N, N'-Bis (2-Hydroxy Benzylidene) Benzidine computed by density functional theory (DFT) using B3LYP/6-311G (d, p) basis set.
