摘要: The acid-catalyzed condensation of pyrrole with p- or m-hydroxyacetophenone led to the formation meso-tetramethyltetrakis(hydroxyphenyl)calix[4]pyrroles occurring in three isomeric forms, cone conformer displaying topologically variable multi-site multi-point surfaces for binding neutral anionic substrates.
