For the conjugated oligoacetylenic systems, a representative example is a compound with six conjugated diacetylene units synthesized by Diederich's group through end-capping polymerization. 8 Molecular wires end-capped with redox-active metal groups have also been reported. 9,10 The longest molecule of this group has up to ten conjugated acetylene units. Novel heterocycles comprising alternating phosphorus atoms and acetylene units reported by ...
