Various boronic acid appended calixarene assemblies were constructed on the macrocyclic lower rim. Treatment of the appropriate calix[ 4] arene with controlled amounts of base and 2-bromomethylphenylethylene boronate affords the monoboronic acid triphenol or the distally separated diboronic acid of choice. Upper rim p-allyl calix[ 4] arene phenyl boronic acids were prepared. These ligands were designed to allow further study of guest complexation in nonaqueous, aqueous and on solid substrates.
