Herein, organic linker-based near-infrared-I (NIR-I) emissive metal-organic frameworks (MOFs), with a maximum emission peak at 741 nm, were synthesized linker engineering. By integration of stronger acceptor and donor groups into one linker, a significant bathochromic-shift is realized. This MOF exhibits great selectivity and sensitivity for aniline and -phenylenediamine detection. This finding provides new insights into the rational design of NIR-MOFs for sensing and related applications.
在此,通过连接体工程合成了基于有机连接体的近红外-I(NIR-I)发射金属有机框架(MOF),其最大发射峰位于741nm。通过将更强的受体和供体基团整合到一个连接体中,实现了显著的红移。这种MOF对苯胺和对苯二胺检测表现出极大的选择性和灵敏度。这一发现为用于传感及相关应用的近红外MOF的合理设计提供了新的见解。
