The discovery and designed synthesis of multifunctional materials is a leading pursuit in materials science. Herein, we report a novel hydro-isocyanurate, NHZn(HCNO), which combines strong second harmonic generation (SHG) and ultra-long room-temperature phosphorescence (RTP). The SHG intensity is the highest within the cyanurate system (13 × KDP), and RTP lifetime extends up to 448 ms, accompanied by a long-lasting afterglow visible to the naked eye for 1.2 s, surpassing most of the current metal-organic complexes. This advancement holds promise for the development of multifunctional optoelectronic devices, particularly leveraging second-harmonic generation (SHG) processes.
多功能材料的发现与设计合成是材料科学领域的前沿追求。在此，我们报道了一种新型的氢异氰尿酸酯NHZn(HCNO)，它兼具强二次谐波产生（SHG）和超长室温磷光（RTP）特性。其SHG强度在氰尿酸酯体系中最高（为KDP的13倍），RTP寿命长达448 ms，伴有肉眼可见的长达1.2 s的持久余辉，超过了目前大多数金属有机配合物。这一进展为多功能光电器件的发展带来了希望，特别是在利用二次谐波产生（SHG）过程方面。
