Pyrene-coumarin Based Calix Fluorophore Emitting Exciplex

摘要

The chemistry of calixarenes,cyclic oligomers composed of phenolic and methylene moieties,has been extensively studied in recent years.The preorganized binding sites,easy derivatization and flexible three-dimensional steric structures make them perfect platforms for sensors to generate fluorescent receptors.Fluorescent chemosensors based on calix[4]arene framework and capability of selectively recognizing heavy metal ions and anions have been studied in fields of chemistry and biology.
