Ligand‐Tuned Perylene Diimide‐Based Versatile Coordination Polymers for Photoluminescent Sensing and Optoelectronics

Abstract Chiral self‐sorting is essential for the establishment of structures in nature and chemistry. Owing to similarities among recognition sites of enantiomers and shared conformational labilities, high‐fidelity chiral self‐sorting constitutes a substantial challenge. Coordination polymers (CPs) with a high surface area and chemical tunability have potential applications in luminescent probes and optoelectronics. However, it is difficult to synthesize micro‐/nano‐scale CPs with high conductivity for optoelectronics. Here, a series of perylene diimide (PDI)‐based CPs with large π‐planes is synthesized by tuning ligands for use in various sensors. A cadmium (Cd)‐based coordination polymer with leucine (LeuPDI‐Cd) exhibits a unique chiral self‐recognition phenomenon when two enantiomeric ligands are mixed with the metal source because homochiral CPs are thermodynamically more stable tha…
