本文报道了一种新型的三周期金属有机骨架（莫伊）单组分发光体的宽带直接白光发射。这种材料具有前所未有的拓扑结构，具有（3，4）连接的节点。该系统中的结构功能关系是由两个互补的独特结构特征驱动的：相互渗透和相互渗透。模拟和实验发射光谱之间的良好相关性已经达到，从而优化的颜色特性，接近固态照明（SSL）的要求。在优化计算光谱的指导下，成功地实现了Eu3+的骨架共掺杂，证明了组装体的可调谐性。这导致显着改善的颜色特性，为合理设计SSL应用的替代材料开辟了新的途径。
Herein we report on the broad-band direct white-light originating from a single component emitter, namely a novel three-periodic metal organic framework (MOE). This material features an unprecedented topology with (3,4)-connected nodes. The structure function relationship in this system is driven by two complementary unique structural features: corrugation and interpenetration. Good correlation between simulated and experimental emission spectra has been attained, resulting in optimized color properties that approach requirements for solid-state lighting (SSL). Guided by the optimized calculated spectra, the tunability of the assembly was proven by the successful in-framework co-doping of Eu3+. This resulted in significantly improved color properties, opening new paths for the rational design of alternative materials for SSL applications.
