Open-Shell and Closed-Shell Quinoid-Aromatic Conjugated Polymers with High Charge Transport and Spin-Magnetic Activity |
| 초록 |
Quinoidal compounds have attracted great attention in organic electronics such as organic field-effect transistors, thermoelectics and organic spintronics. They possess a highly planar structure due to a double bond linkage between each ring, and have interesting and unique features such as low band-gap, redox amphoterism and spin-induced magnetic activity. Their electronic states were controlled by the core length. When the quinoid structure is extended, it tends to form an open-shell diradical form to recover aromaticity. So far, their structure-property relationship remains as a fundamental question. Here, we developed and characterized two quinoid-aromatic conjugated polymers incorporating quinoids with different lengths, which have a closed/open-shell character, respectively, namely, PQuT-TV and PQuBT-TV. We successfully demonstrated how the control of the closed/open-shell character of quinoids changes charge transport and spin properties of quinoid-aromatic conjugated polymers. |
