Studies On Synthesis And Properties Of Several Novel Thiacalix[4]Arene-Bridged Polyether And Crown Ether Receptors

Thiacalix[4]arene is an excellent building block widely used for construction of novel optical-and redox-active supramolecular receptors through chemical modification to incorporate diverse recognition moieties and probes.These receptors may be potentially applied to test their optical and electrochemical responding to the desired substrates.In recent years,many optical-active thiacalix[4]arene-based receptors have been reported,while few of redox-active such receptors were descibed.And hence this dissertation is an account of the design,synthesis,and supramolecular properties of novel redox-active thiacalix[4]arene receptors.It is divided into three sections.In the first part,recent research progress of both cone and 1,3-alternate thiacalix[4]arene-bridged polyether and crown ether receptors,including molecular design,chemical synthesis and their applications in the fields of supramolecular recognition,was briefly reviewed.In the second part,three new thiacalix[4]arene-bridged polyether receptors with ferrocene amide or urea termini were designed and synthesized.Their structures were characterized by 1H NMR,13C NMR,IR and HR-MS,as well as for two typical derivatives being determined by X-ray diffraction techniques.The recognizing and sensing properties for some ions were evaluated using UV-Vis,fluorescence and cyclic voltammertry techniques.It was found that they show a good recognition for Cu2+、Eu3+ and H2PO4-ions.In the last part,five novel ferrocene bisamide-containing thiacalix[4]arene-bridged crown ether receptors incorporating various tunable groups were designed and synthesized.Their structures were characterized by 1H NMR,13C NMR,IR and HR-MS,as well as for three receptors being determined by X-ray diffraction techniques.Their tunable effect and sensing properties for some ions were evaluated with UV-Vis and cyclic voltammertry techniques.
