  Phosphate selective alkylenebisurea receptors: structure-binding relationship

  摘要：

  New host molecules for anions, adamantane, and alkyl urea derivatives substituted by naphthalene chromophores, were synthesized. Their binding with F-, Cl-, Br-, OAc-, HSO4-, NO3-, and H2PO4- was investigated by UV-vis, fluorescence and NMR spectroscopy. The anion binding ability of adamantyl bisurea derivatives was compared with the analogous host molecules, wherein the urea moieties are separated by flexible alkyl linkers of the same length, and adamantane monourea derivative. The host molecules show the highest selectivity toward F- and H2PO4-. The binding stoichiometry and the values of the association constants depend on the basicity of anions, availability of H-bonding sites, preorganization, and rigidity of the hosts, as well as solvent polarity and H-bonding availability. Rigid adamantane receptors, compared to flexible analogues show increased selectivity for H2PO4-, whereas binding of OAc- is better with flexible receptors. The binding of OAc- and H2PO4- was investigated by microcalorimetry. The stoichiometries and the stability constants of the corresponding complexes obtained by this method were in good agreement compared to those determined by UV-vis titrations. In both cases the enthalpic contribution to the overall complex stability was predominant. (C) 2011 Elsevier Ltd. All rights reserved.

  Adamantaneurea derivatives 1–13 were synthesized and their photophysical properties investigated. The compounds 1–13 are comprised of a rigid adamantane moiety, 1 or 2 urea groups and different chromophores, as well as methylene spacer between the adamantane and the urea and/or between the urea and the chromophores. Fluorescence quantum yields and singlet excited state lifetimes were measured in CH3CN
