Dichromate is one of widespread contaminants in wastewater, it has threatened the health of human and other organisms. Therefore, effective detection and removal of dichromate from water is of great significance. Herein, a tetraphenylethylene functionalized cationic organic network (CON-LDU2) was constructed via a facile quaternization reaction. CON-LDU2 was successfully integrated with both detection and removal functionalities towards dichromate. On the one hand, benefitting from the strong fluorescence, CON-LDU2 was employed as a chemosensor, it could efficiently and selectively probe Cr2O72- in water with “”turn-off”” fluorescent response. On the other hand, the cationic skeleton and free anions inside framework make CON-LDU2 an excellent adsorbent for Cr2O72-, it could capture Cr2O72- from water with rapid kinetic and high capacity. The kinetic constant for adsorption of Cr2O72- can reach up to 1.784 g mg-1 min-1, while the capacity is determined as 325 mg g-1. Furthermore, CON-LDU2 displayed good recyclability and can be reused at least for 5 cycles. Therefore, CON-LDU2 can serve as an ideal candidate not only in detection but also in removal of Cr2O72- in water medium. After reading the article, we found that the author used 1,4-Bis(bromomethyl)benzene(cas: 623-24-5Formula: C8H8Br2)
1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds.Organobromine chemicals are produced naturally by an array of biological and other chemical processes in our environment. Some of these compounds are identical to man-made organobromine compounds, such as methyl bromide, bromoform, and bromophenols, but many others are entirely new moleclar entities, often possessing extraordinary and important biological properties.
