Abstract
New through-space conjugated polymers comprising the pseudo-ortho-linked [2.2]paracyclophane moiety were synthesized by the Sonogashira coupling reaction. All the synthesized polymers were soluble in common organic solvents and could form thin films. The UV–vis absorption spectra of the synthesized polymers revealed an extension of the conjugation length owing to the through-space interactions. The polymers exhibited a blue-light emission in both solution and film states.
