Zimmerman, Steven C. published the artcileAnalysis of Amidinium Guest Complexation by Comparison of Two Classes of Dendrimer Hosts Containing a Hydrogen Bonding Unit at the Core, Synthetic Route of 14903-78-7, the publication is Journal of the American Chemical Society (1998), 120(9), 2172-2173, database is CAplus.
Host-guest complexation studies were performed using two isostructural series of hosts to determine the accessibility and nanoenvironment of dendrimer cores. Association constants (Kassoc) were measured by 1H NMR for the hydrogen bonded complexes formed between hosts and guests 3,5-di-tert-Bu benzamidinium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate and 3,5-bis(3′,5′-di-tert-butylphenylacetylene) tetrakis[3,5-bis(trifluoromethyl)phenyl]borate in 10% acetonitrile-d3/chloroform-d. The results indicated site-specific binding between the dendrimer core and small guest mols. The on-off rates were fast on the NMR time scale even for complexes formed from high generation number hosts. Strikingly, the two series of dendritic hosts exhibited very similar complexation strengths even though the rigidity and polarity of the dendrimer interiors were quite different.
