✦ Synopsis

Porphyrin dimer linked with chiral binaphthyl derivative was prepared as a ditopic eoreceptor for a series of diamines. Its zinc complex shows the good affinity for ct,o~-diamines H2N(CH2)nNH2 (n = 6, 8, 10, 12; Ka = 105 -106 M -1 in CH2C12 at 15 °C). These complexes gave the significant bisignate CD spectra due to the exciton coupling between two zinc porphyrins and its intensity depends on the length of diamine. The CD spectrum in the complex reflects angle and flexibility of the chiral twist between two zinc porpbyrin units.

A new ditopic receptor 2 consisting of a meso-ternaphthalene backbone and two crown rings has been shown to selectively complex and transfer dipicrate of 1,9-diaminononane and 1,10-diaminodecane from aqueous solution into the organic phase.
