Abstract

(Equation Presented). A cyclic porphyrin trimer has been synthesized which has a high affinity for fullerenes. It forms 1:1 complexes with C₆₀ and C₇₀ with association constants of 2×10⁶ and 2×10⁸ M^-1, respectively, in toluene. Its affinities for C₈₆ and La@C₈₂ are too strong to measure by fluorescence titration. The solvent dependence of the association constants shows that solvation of both the guest and the host influence the binding strength.
