Heterodimerization studies of calix[4]arene derivatives in polar solvents
Several calix[4]arene derivatives propylated on the lower rim and substituted on the upper rim with amino or carboxyl groups have been synthesized. Examples include calixarenes substituted with alanino (C- and N-linked), amino, carboxy, carboxyphenyl, and

Phenyl-calix[4]arene-based fluorescent sensors: Cooperative binding for carboxylates
Tetrakis-(4-carbamoylphenyl)-substituted and tetrakis-(4-amidophenyl)- substituted calix[4]arenes as well as the monomeric biphenylcarbamate have been synthesized as fluorescent receptors for anion sensing. Their binding properties with various anions inc
