Condensation of resorcinol with phosphorylated acetals, synthesis of calix[4]resorcinolarenes with phosphorus-containing alkyl fragments in the lower rim

The reaction of resorcinol with phosphorylated acetals leads to formation of calix[4]resorcinolarenes having phosphonate, phosphinate, or (phosphinothioyl)sulfanylmethyl fragments in the lower rim of the molecule.

Synthesis and fluorescent properties of thiacalix[4]arenes containing terpyridyl fragments at the lower rim

New thiacalix[4]arenes tetrasubstituted by terpyridyl fragments at the lower rims in the 1,3-alternate stereoisomeric form were synthesized. The molecules interact with Eu^III and Tb^III in the DMF solution to form highly luminescent nanoscale (21–26 nm) metal-organic structures with the 2: 1 metal-to-ligand stoichiometry and a narrow particle size distribution.
