摘要
Compounds 2-6 were synthesized by starting from the pyridine-bridged calix[6]arenes 1. Most of these derivatives exist in a concave conformation like their parent compounds 1, but in some cases the conformational behavior is different. Relative basicities of 1-6 and of the open-chain model compounds 7 were measured by a photometrical titration against thymol blue. An unexpectedly high basicity of 1-4 was found.
