Buried solvent determines both anion-binding selectivity and binding stoichiometry with hydrogen-bonding receptors

Burns, Dennis H.; Calderon-Kawasaki, Kenichi E.; Kularatne, Sumith (American Chemical Society, 2005-04-01)

The crystal structure of a tetraurea picket porphyrin-chloride anion complex has previously shown the anion to be situated between two adjacent ureas and hydrogen bonded via four NH protons (J. Am. Chem. Soc. 1998, 120, ...
Synthesis of urea picket porphyrins and their use in the elucidation of the role buried solvent plays in the selectivity and stoichiometry of anion binding receptors

Calderon-Kawasaki, Kenichi E.; Kularatne, Sumith; Li, Yue He; Noll, Bruce C.; Scheidt, W. Robert; Burns, Dennis H. (American Chemical Society, 2007-11-23)

The synthesis of alpha,alpha-5,10-diurea and alpha,alpha,alpha-5,10,15-triurea picket porphyrins are detailed in this report. In previous reports, these porphyrins, along with alpha,alpha,alpha,alpha-5,10,15,20-tetraurea ...
