摘要

The first neutral pi-conjugated polyradical based on phenalenyl with the spin unit inside the main chain was prepared. Cyclic voltammetry studies showed that this polyradical had excellent redox reversibility and enhanced pi-delocalization between the neighboring spin units, in consistent with the UV-vis results. Initial magnetic studies showed that a strong antiferromagnetic interaction existed at solid state. The conductivity of the polyradical was measured with a value sigma(RT) approximate to 10(-8) S/cm.
