|Title:||Polarons, Bipolarons, And Crystallization In Conducting Polymers: An Esr Study|
|Abstract:||Electron spin resonance (ESR) experiments give extremely important information concerning spin arrangements in conducting polymers. This is evidenced by the behavior of the ESR lines as a function of temperature and microwave power. Our ESR data of pressed pellets of ClO-4 doped poly(3-methylthiophene) (P3MT) synthesized at 25 °C show the predominance of polarons. Instead, the sample prepared at 5 °C shows the predominance of bipolarons. Besides, for both types of samples, crystallization, observed from the ESR data, has shown a rearrangement of spin species.|
