A comparative molecular structure–NLO activity study of ortho-bridged dibenzaldehydes: Synthesis, crystal structure, SHG, and DFT studies
Structural and second order nonlinear optical characteristics of four ortho-bridged
dibenzaldehydes with alkyloxy-and xylenyloxy linkers are compared from the XRD, UV-Vis-
NIR spectroscopic, SHG, and DFT studies. Interruption of electron polarization by π-
conjugation of the linkers between the two benzaldehyde units affect their NLO properties
like hyperpolarizability (β) in these acceptor–π–bridge–donor–π–bridge–acceptor (A–π–D–
π–A) systems. The noncentrosymmetric 2, 2′-[1, 2-phenylenebis (methylenoxy)] …
