Abstract

A new SHG material, namely, Pb2 (BO3 )(NO3 ), which contains parallel π-conjugated nitrate and borate anions, was obtained through a facile hydrothermal reaction by using Pb(NO3 )2 and Mg(BO2 )2 ⋅H2 O as starting materials. Its structure contains honeycomb [Pb2 (BO3 )]∞ layers with noncoordination [NO3 ](-) anions located at the interlayer space. Pb2 (BO3 )(NO3 ) shows a remarkable strong SHG response of approximately 9.0 times that of potassium dihydrogen phosphate (KDP) and the material is also phase-matchable. The large SHG coefficient of Pb2 (BO3 )(NO3 ) arises from the synergistic effect of the stereoactive lone pairs on Pb(2+) cations and parallel alignment of π-conjugated BO3 and NO3 units. Based on its unique properties, Pb2 (BO3 )(NO3 ) may have great potential as a high performance NLO material in photonic applications.
