Discovery of NLO Semiorganic (CHON)(HPO): Dipole Moment Modulation and Superior Synergy in Solar-Blind UV Region.

We herein report a novel semiorganic NLO material, (CHON)(HPO), 4HPP, showing promising excellent properties in the important solar-blind UV region where LAP and its deuterated form DLAP are the only commercialized semiorganic materials. For the first time, the 4-hydroxypyridine (4HP, (CHON)) cation is identified as NLO active and how to eliminate the dipole-dipole interaction to avoid the unwanted center-symmetry-trap caused by the polar-induced susceptibility is well demonstrated. Remarkably, 4HPP exhibits competitive and even better properties compared with LAP that include better thermal stability (decomposition at 166 vs 112 °C of LAP); wider transparency range (0.

How To Maximize Birefringence and Nonlinearity of π-Conjugated Cyanurates.

Materials with large birefringence (Δ) are highly needed by fiber-optic isolators, whereas crystals showing strong second-order harmonic generation (SHG) are the key component for all-solid-state laser devices. Cyanurate constructed by the planar π-conjugated ring (CNO, CY) is a class of fascinating materials exhibiting not only very large Δ (larger than that of calcite) but also strong SHG (2 times that of β-BaBO, BBO). Here, we report five new cyanurates (-) and their single-crystal structures; among them, realizes a Δ = 0.
