The removal of plastics from wastewater has been extensively investigated through diverse methodologies over the years.1-3 Fe-catechol-based Metal-Organic-Frameworks (MOFs) have emerged as efficient and sustainable materials for nanoplastic removal, offering a green approach toward environmental remediation. With this overview, a series of non-fused and fused ligands were synthesized via Suzuki-Miyaura cross-coupling reaction. The derived ligands were found to exhibit solvatochromism. The excited dipole of the ligands was found to be stabilized in polar solvents. MOFs were developed from the corresponding ligands. Iron, one of the most abundant metals, combined with readily available precursors for the ligands, offers a highly promising route for scalable synthesis and subsequent applications in delivering excellent efficiency on adsorbing very small nano-sized plastics, derived from PVC-SDS-PTE moiety.
