PO(CH₂CH₂CF₃)₃: an organic ultraviolet nonlinear optical material without any anionic group.

ABSTRACT: Researchers have focused on inorganic compounds to design deep ultraviolet (UV) nonlinear optical (NLO) materials according to anionic group theory, such as CO₃ ^2-, NO₃ ^-, SO₄ ^2- and PO₄ ^3- anions. Here we provide a new route to design an UV NLO material using a pure organic compound without any anions. Compound PO(CH₂CH₂CF₃)₃1, an UV NLO material, has light transmittance up to 83% in the UV spectral region which is larger than most inorganic UV NLO materials. It also displays a wide transparent band, a SHG response of 0.30 × KH₂PO₄, and a cut-off edge below 200 nm. It displays ladder-like nonlinear optical properties weakened by 1.4 time
