Crown ethers and phthalocyanines are both important molecules in coordination chemistry.  Crown ethers can selectively bind alkali and alkali earth metal ions based on size for organic solvent applications, and the metal complexes of the phthalocyanines have many uses in materials applications.   In this poster, we present a new class of molecules we call the phthalocrowns, chimera molecules composed of a crown ether and phthalocyanine.  These compounds are synthesized via Schiff base-type condensation reactions between polyetherdiamines and diiminoisoindoline, which can be generated from phthalonitrile.  We are currently producing macrocycles with two, three and four ether groups appended to diiminoisoindoline, and are characterizing these compounds with methods including X-ray crystallography.   The purpose of this project is then to study the ability of these new molecules to bind cations, including main group and/or transition elements.
