摘要
In this work, we have synthesized and characterized bis-urea derivatives 1-3, featuring a biphenyl spacer, and studied their anion binding properties in DMSO solution and in the solid state. In solution, 1:1 complexes were observed with association constant K values in the 10(3)-10(4) M-1 range with a general preference for acetate over dihydrogenphosphate for all three receptors. We were also able to obtain and characterize, by X-ray diffraction on single crystals, ten receptor-anion complexes including acetate and dihydrogenphosphate, as well as monohydrogenphosphate, halides and the nitrate ion. Linear (anion-receptor)(n) arrays, porous frameworks and non-centrosymmetric structures were observed and described in detail.
