Synthesis and association behavior of butadiyne-bridged [44](2,6)pyridinophane and [46](2,6)pyridinophane derivatives
(matrix presented) Butadiyne-bridged [44](2,6)pyridinophane and [46](2,6)pyridinophane derivatives were synthesized, and their heteroassociations with the corresponding metacyclophanes and complexations with organic cations were investigated.
