“…However, it has long been overlooked. To our best knowledge (see Supporting Information, Table S1), there are only four noncentrosymmetric cyamelurate crystals − and not any reports about their NLO properties. Here, we obtained a new acentric metal cyamelurate K 3 C 6 N 7 O 3 ·2H 2 O ( I ).…”

The delocalized π-conjugated units are considered as an advantageous gene for improving the optical nonlinearity of acentric crystals. For the first time, we synthesized a new acentric SHG-active metal cyamelurate crystal K 3 C 6 N 7 O 3 •2H 2 O (I) by a facile solution method, containing a colossal planar π-conjugated (C 6 N 7 O 3 ) 3− unit. It displays a strong second-order harmonic generation (SHG) of 4 × KDP and a giant anisotropic birefringence of 0.446 at 1064 nm. The theoretical calculations reveal that such substantial improvement is contributed from the strong molecular susceptibility of (C 6 N 7 O 3 ) 3− units and their near-perfect coplanar arrangement. Moreover, I exhibits a broadband ultraviolet photoluminescence at 366 nm, suggesting its multifunctional capacity and great potential for compact highly integrated optoelectronic devices.
