已经合成了对富勒烯具有高亲和力的环状卟啉三聚体。它在甲苯中与 C-60 和 C-70 形成 1:1 配合物，缔合常数分别为 2 x 10(6) 和 2 x 10(8) M-1。它对 C-86 和 La@C-82 的亲和力太强，无法通过荧光滴定来测量。缔合常数的溶剂依赖性表明客体和主体的溶剂化都会影响结合强度。
A cyclic porphyrin trimer has been synthesized which has a high affinity for fullerenes. It forms 1:1 complexes with C-60 and C-70 with association constants of 2 x 10(6) and 2 x 10(8) M-1, respectively, in toluene. Its affinities for C-86 and La@C-82 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.
