A β-to-β2,5-thienylene-bridged cyclic porphyrin tetramer: its rational synthesis and 1 : 2 binding mode with C60†
Abstract
A β-to-β2,5-thienylene-bridged cyclic porphyrin tetramer was rationally synthesized via a concise synthetic route. The tetraporphyrin exhibits a positive cooperative binding ability to C60 and demonstrates a new potential of the nonplanar, distorted cyclic
