摘要

A convergent '3+ 1'synthesis allowed a simple entrance to the first examples of [14] metaazolophanes 1 and [14](meta-ortho) 2azolophanes 2 built up from heterocyclic betaine subunits, illustrating a prototype of phanes constructed by both highly π-excessive and highly π-deficient heteroaromatic moieties linked in a 1, 3-alternating fashion.
