Characteristics of structure, thermal stability and optical properties for a novel NLO crystal (C5H12NO)H2PO4

Designing promising ultraviolet (UV) birefringent crystals with different hydrogen-bonded phosphate frameworks

“…5). Compound I demonstrates a superior SHG response compared to certain reported semiorganic phosphates, such as (C 3 H 7 N 6 ) 6 (H 2 PO 4 ) 4 (HPO 4 )·4H 2 O (0.1 × KDP) 40 and (C 5 H 12 NO)H 2 PO 4 (0.15 × KDP), 58 and is comparable to [C(NH 2 ) 3 ] 2 HPO 4 ·H 2 O (1.2 × KDP) 59 and [C(NH 2 ) 3 ] 2 PO 3 F (1.0 × KDP). 60 However, it underperforms in SHG effect relative to [C(NH 2 ) 3 ]PO 4 ·2H 2 O (1.5 × KDP), 38 [C(NH 2 ) 3 ] 6 (PO 4 )·3H 2 O (3.8 × KDP), 39 and (C 5 H 6 ON) + (H 2 PO 4 ) − (3.0 × KDP).…”
