Synthesis of through-space conjugated polymers containing the pseudo-ortho-linked [2.2]paracyclophane moiety
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.
