Exfoliation of a Coordination Polymer Based on a Linear π-Conjugated Ligand into an Ultrathin Nanosheet for Glyphosate Sensing

“…As a type of inorganic–organic hybrid material, coordination polymers (CPs) are assembled from the coordination between organic linkers and metal cations/clusters with repeating coordination entities extending in 1, 2, or 3 dimensions and have emerged as one of the most fascinating candidates of luminescent materials in the field of fluorescence sensing, − light-emitting diodes (LEDs), , bioimaging, nonlinear optics (NLOs), , upconversion materials, , and so on, due to tunable luminescence properties. , Among various CPs, the entities with potential voids that are usually well-known as porous coordination polymers (PCPs) or metal–organic frameworks (MOFs) have been of the most concern and gained tremendous success in various fields due to structural diversity, high porosity, large surface area, and easy modification. − Additionally, external stimuli can induce significant changes in the fluorescence properties of CPs through varieties of mechanisms, including structure transformation/collapse, size exclusion, energy transfer, photoinduced electron transfer (PET), guest exchange, and so on, − which offer the feasibility of employing CPs to serve as fluorescent sensing materials. Thus, tremendous efforts have been devoted to the exploration of CPs as fluorescent sensors and quantities of CPs have displayed outstanding fluorescence sensing performance for varieties of chemicals, including hazardous gas, volatile organic compounds (VOCs), explosives, pesticides, antibiotics, amino acids, or parameters such as pH and temperature. , Although various metal cations could be employed to prepare CPs, transition metal cations with d 10 electron configuration, especially Zn­(II) and Cd­(II), are of special concern in the construction of fluorescent CPs due to their potential superior fluorescence properties originating from the possible ligand-to-metal charge transfer (LMCT) process. ,− …”
