摘要：

[GRAPHICS] Porphyrin tetramer 1 was newly designed and synthesized to construct a novel cooperative [60]fullerene (C-60) binding system. Compound 1 has a p-terphenyl axis, which is expected to act as a scaffold for a guest-binding information transducer. In toluene, 1 can bind 2 equiv of C-60 to produce a 1:2 1/C-60 complex with association constants of 5800 M-1 (K-1) and 2000 M-1 (K-2). These values are significantly greater than those for control porphyrin dimers such as 2 and 3.
