Gong, J.; Gibb, B. C. A new macrocycle demonstrates ditopic recognition properties. Chem. Commun. 2005, 1393-1395.

The synthesis and binding properties of a new macrocycle is reported. The host, comprised of three basic pyridines, four hydrogen bond accepting carbonyls, and two hydrogen bond donating amide groups, binds mono-alkyl ammonium salts in a manner that is dependent on the counter-ion of the ammonium guest.


Kaanumalle, L. S.; Gibb, C. L. D.; Gibb, B. C.; Ramamurthy, V. A Hydrophobic Nanocapsule Controls the Photophysics of Aromatic Molecules by Suppressing Their Favored Solution Pathways. Journal of the American Chemical Society 2005, 127, 3674-3675.
A combination of hydrophobic forces and guest templation drive the assembly of cavitands into molecular capsules. Remarkably, anthracene that dimerizes with unit efficiency in solution does not dimerize within the capsule despite forming 2:2 complex. The capsule allows an unprecedented examination of the anthracene excimer.
