概要 | The synthesis and selective mol. recognition of a new type of cylindrical, macrotricyclic receptor (I) having crown ether and cyclophane subunits as binding sites and a large hydrophobic cavity are described. Receptor I was synthesized by the stepwise construction of three individually prepd. subunits: bis(p-toluylsulfonamido)dibenzo-18-crown-6, a diaminocyclophane, and Et 4'-(bromomethyl)biphenyl-4-carboxylate. The interaction of I and various (ω-phenylalkyl)ammonium picrates, for which the no. of methylene units varies from 3 to 9, was examd., and they were found to form 1:1 complexes. The selectivity of I for the picrates was evaluated by comparing the stability consts. (Ks') of these complexes. The Ks' values of the complexes with (5-phenylpentyl)ammonium and (6-phenylhexyl)ammonium picrates were more than 3 times as large as those of the other complexes; i.e., I showed selective mol. recognition. |
