摘要：

Syntheses are described for two octatetrayne-linked cyclic porphyrin oligomers with extremely spacious cavities. These hosts bind strongly to complementary multidentate guests. Thus, the octatetrayne-linked dimer binds bifunctional ligand bis(4-pyridyl)ethyne with an affinity of 7 x 10(6) dm(3) mol(-1), and the trimer binds the new 'stretched' trifunctional ligand 1,3,5-tris[(-pyridyl)ethynyl]benzene with an affinity of 2 x 10(8) dm(3) mol(-1) in C2H2Cl4 at 30 degrees C.
