Synthesis of New Photoswitchable Tectons Based on Thiacalix[4]arene Azo Derivatives in the 1,3- Alternate Conformation

摘要

The paper describes the first synthesis of molecular tectons, a series of ligands based on thiacalix[4]arenes in the 1,3- alternate stereoisomeric form containing photoswitchable azo groups in the side chain and carboxyl groups as potential binding sites for the synthesis of photoswitchable complexes and coordination polymers. In the case of p - tert -butylcalixarenes, the convergent approach is preferred.
