A novel, gas phase, host-guest molecular recognition process, detected
by electrospray ionization mass spectrometry, using guests that encom
pass aromatic amino acids and aromatic and aliphatic carboxylic acids
with a supramolecular, bioorganometallic host, [CpRh(2'-deoxyadenosin
e)](3)[OTf](3) (Cp = eta(5)-C5Me5), is found to occur predominately v
ia non-covalent pi-pi interactions; non-covalent hydrophobic forces ap
parently being weak or non-existent.
