This Letter reports the results of our studies towards the synthesis of thiacalixarenes. In an effort to develop an efficient and inexpensive synthetic methodology for thiacalixarenes, several trials were conducted to study the effect of base/template, solvents, catalyst, phenol substitutions and temperature profile. Microwave synthesis was also tested to reduce the overall time for the reaction....
New chromogenic supramolecular vanadophiles were designed and synthesized by incorporating hydroxamic acid chains on a 1,3-alternate thiacalix[4]arene scaffold and were found to show high affinity toward vanadate ions. The article describes a comprehensive design process to devise a tailor-made co-ordination cavity for vanadate ions by pre-organization of hydroxamic acid chelating moieties on a 1,3-alternate...
