To investigate the manipulation of electromagnetic properties of two-dimensional materials, this effort characterizes charge transfer behavior of colloidal COF-5 (covalent organic framework) in the presence of various metal ions. A series of metal chloride compounds was introduced to COF-5 in solution and solid film phases and the interaction of the material with electromagnetic radiation was monitored across the visible region using electronic absorption spectroscopy. Notable changes were observed, quantified, and discussed for copper (II) chloride (CuCI2), chromium (III) chloride (CrCI3), and iron (III) chloride (FeCI3) with COF-5. Ligand-to-metal and metal-to-ligand charge transfer are explored as a possible mechanism for the observed electronic behaviors.

COF-5溶液和金属离子嵌入薄膜的电子电荷转移特性

为了研究二维材料的电磁特性的操纵,这项工作表征了胶体 COF-5(共价有机骨架)在各种金属离子存在下的电荷转移行为。将一系列金属氯化物化合物以溶液相和固膜相引入 COF-5,并使用电子吸收光谱法在整个可见光区监测材料与电磁辐射的相互作用。使用 COF-5 观察、量化和讨论了氯化铜 (II) (CuCl2)、氯化铬 (III) (CrCl3) 和氯化铁 (III) (FeCl3) 的显着变化。探索了配体到金属和金属到配体的电荷转移作为观察到的电子行为的可能机制。
