Molecular recognition in a uradinyl-functionalized stable radical

Patrick Taylor, Paul M. Lahti, Joseph B. Carroll and Vincent M. Rotello

Stable radical 2-(6-uradinyl)-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazole-1-oxyl ( 1) binds to hydrogen-bonding complement 2,6-di(propylamido)pyridine (DAP) in chloroform with Ka= 220 M–1 at 33 °C; ESI-MS shows not only 1DAP complementary dyad formation, but also 1(DAP)2 formation at higher concentrations of DAP.
