"clickable" thiacalix[4]arene derivatives bearing polymerizable 1,3-butadiyne fragments: Synthesis and incorporation into polydiacetylene vesicles

Abstract

p-tert-Butylthiacalix[4]arene derivatives in 1,3-alternate stereoisomeric form bearing polymerisable 1,3-butadiyne fragments on the one side and amino/carboxylic groups on another were synthesized using stepwise functionalisation. Calixarene 7 embedded in polydiacetylene nanoparticles showed a selective colorimetric response toward lanthanide ions.
