摘要：
Copolymers of m-phenylene and 1,3,5-triazine were synthesized. The polymers had a π-conjugated thiophene-based unit as a p-dopable side chain. The polymer having a 3,4-ethylenedioxythiophene-based unit was oxidized by treatment with NOBF4, and this p-doped polymer exhibited a magnetic hysteresis loop at 5 K.
