| Abstract: | New adamantane-dipyrromethanes (AdD 1-4) were synthesized and their anion binding properties investigated. AdD 1-3 form 2:1 complexes with F− (AdD:F = 2:1) characterized by high association constants, and 1:1 complexes with Cl−, Br−,  and  . The binding of Cl−, Br−,  and  by AdD 1-3 is 2-3 times stronger than for the reference compound, meso-phenyldipyrromethane (5). However, AdD 4 forms complexes with F− characterized by 1:1 and 1:2 stoichiometry (AdD:F = 1:2). |
