OCTATETRAYNE-LINKED PORPHYRINS - STRETCHED CYCLIC DIMERS AND TRIMERS WITH VERY SPACIOUS CAVITIES
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 × 10 6 dm3 mol-1,...
