- Abstract
Three stereoisomers ( cone, partial cone, and 1, 3- alternate) of p- tert-butylthiacalix[4]arene bearing four anchor propyltriethoxysilane substituents at the lower rim were synthesized for the first time. Surface modification of silica nanoparticles ( d = 12 nm) with the synthesized macrocycles gave novel hybride thiacalix [4]arene-SiO particles. The obtained nanostructured adsorbents were found to efficiently extract nitroaromatic compounds from aqueous solutions. The partial cone and 1,3- alternate thiacalix[4]arene-SiO hybrid particles showed affinity to nitrophenols.
