Article abstract of DOI:10.1016/S0040-4039(00)84749-8

Two new hemispherands 2a and 2b containing a central 4H-pyran unit were synthesized via appropiately substituted 2,6-phenyl pyrylium salts; largest ΔG⁰ values of complexation of 2a and 2b with different alkali picrates are found for Na(+) and K(+).
