Abstract

The synthesis of several chiral porphyrin host compounds is reported. The hosts were synthesized from the reaction of a porphyrin isocyanate with chiral piperidine and pyrrolidine derivatives. The chiral recognition properties of these porphyrin-based hosts with chiral carboxylate-containing guests is described. A unique aspect of the hosts is their introverted functionality � guest recognition motifs protrude into the interior of the host cavity where they work in tune with the porphyrin metal center for cooperative guest binding. Several hosts display a conformationally-induced organization upon binding to guests similar to that observed in protein chemistry. Binding constants of the chiral porphyrin hosts with guests, which was determined by UV/Vis titration studies, will be reported.
