Several Kinds Of Light, Electricity Active Sulfur Impurity Cup [4] Arene Receptor Molecules Synthesis And Properties Of The Research

Investigation on supramolecular chemistry and materials science based onthiacalix[4]arenes has attracted extensive attention, not only because of it’s importanttheoretical significance, but also it’s broad application prospects in the field of iontransport, molecular devices, chemical sensors and molecular switches. The mostinteresting field is thiacalix[4]arene-based crown ether receptors since the introductionof crown ether parts can coordinate its conformation and offer a new three-dimensionalcavity with thiacalix[4]arene to complete the recognition process. Therefore, the designand synthesis of highly preorganized optical and redox active receptors is of greatsignificance. This dissertation is an account of the design, synthesis, andsupramolecular properties of novel thiacalix[4]arene-based optical and redox activityreceptors. It is divided into three sections.The first part briefly reviews the recent research progress of thiacalix[4]arene-based optical and redox active receptors, including molecular design, chemicalsynthesis and their applications in the fields of supramolecular recognition and sensing.The second part design and synthesis of three novel allosteric regulated receptorsthrough the selective modification of anthraquinone triazole-based optical and redoxactive thiacalix[4]arene crown-ether receptor in the cone conformation. Theirstructures were characterized by IR,¹H NMR,¹³C NMR and HR-MS. Due to theregulation function of the side arms of thiacalix[4]arene platform, such receptors showselective recognition functions towards Ag⁺ and Zn²⁺ ions, respetively.The last part involves the synthesis and supramolecular recognition properties oftwo novel cone conformation thiacalix[4]arene receptors bearing optical and redoxactive quinoline and ferrocene probes, respectively. Their structures were fullycharacterized by IR,¹H NMR,¹³C NMR and HR-MS. Preliminary supramolecularrecognition study displayed that two receptors showed ion recognition propertiestoward a variety of metal ions.
