Optical Properties of Conducting Polymer Poly(3-Alkylthiophene) Solution

도전성 고분자 Poly( 3- Alkylthiophene ) 용액의 광학적 성질

In this study, we have studied the optioal properties and $I_2$ doping effect of Poly(3-Akkylthiophene) solution. The end of speotrum absorbance on the solutions of Poly(3 - Octylthiophene), Poly (3-Dodecylthiophene) and Poly(3-Dooooylthiophene) was dependent on temperature. It is bellved that conrod-coil transition dependent on temperature was rod-coil transition. And absortance peak of Poly (3-Dodecylthiophene) in dichloromethane solution increased with increasing the $I_2$ dopant.
