Preserved Fulltext
A β-to-β 2,5-thienylene-bridged cyclic porphyrin tetramer was rationally synthesized via a concise synthetic route. The tetraporphyrin exhibits a positive cooperative binding ability of C 60 to demonstrate a new potential of the nonplanar, distorted cyclic porphyrin arrays. Since the crystal structure of LH2 was elucidated to be 10 25 / ‡ Crystallographic data for 4Zn: C264H288N16S4Zn4, M = 4074.94, tetragonal, space group I-42d (#122), a = 41.392(14), c = 22.518(7) Å, V 45
