Abstract:
In this study, a copolymer from 1,1'-dibromoferrocene and a chiral phenylenediamine was synthesized via Buchwald-Hartwig polycondensation. Characterization of the resulting polymer was performed by using scanning electron microscopy, optical spectroscopy, electron spin resonance, and a superconducting quantum-interference device. The polymer possesses optical activity and exhibits circularly polarized luminescence, which is attributed to the helical conjugated architecture. The polymer thus synthesized exhibits multiple spin states evaluated with electron spin resonance and antiferromagnetic behavior at low temperatures.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
